zero touch migration of Cisco IP phones… Free

Yep, for free and for a limited time .. read on.. UnifiedFX has released a pretty cool tool called #MigrationFX for migrating old Cisco Phones to new. if you take into consideration the time taken to plan and swap phones accross this works out to be a very good solution.

the process is as simple as ordering new phones and distributing to users; no need to scan MAC addresses and allocate and configure for user and ship to THAT user. once user/s receive the phone, its as simple as unplugging the handset and using the same cable adding the new device. this then kick starts the auto provisioning process.

to see how this works see the following link

you can try out the product for free for upto 50 phones, by registering with them http://www.unifiedfx.com/migrationfx-lab-edition/.

and i know you are thinking, but you said for FREE.. and yep im coming to that, if your migration includes more than 100 phones, Cisco will throw this product in for free by using the following promo code L-CP-MGFX-PROMO= in the same TMP registration.

ive been asleep..well not exactly

wow, its been what seems like a long time since I did a post on this site. 3 years long!. so where have I been? well.. for starters I completed my CCIE Voice journey back in 2012, have got involved with some amazing Cisco UC projects, completed my MCSE Communications early this year.

what are you doing now? I am now working in a Service Provider setting doing Video (mostly Cisco), so learning new things every day.

a lot has changed in the last few years in this area, we now no longer talk about dispersed and disjointed communication methods, communication is not primarily only voice. there are multiple areas that the vendors have now consolidated on to provide a truly unique experience internal or external to the enterprise.

Microsoft Lync (now SfB) took the market by storm. While they do not  provide a complete end2end solution, in complex areas of telephony lack ability to deliver and rely on heavily UCOIP partners to fill the void, they have definitely reignited and reinvented the meaning and vision of unified communications and collaboration.they have provided a new perspective to the meaning of Collaboration especially when communicating from the Edge, and with their monopoly over Skype. yea the experience is not always great but from the end user perspective its familiar, easy and pretty intuitive.

From a Cisco perspective, all systems went about their business their own way, there was a massive disconnect in their approach and the story of UC was constantly changing; this has now been drastically consolidated into a preferred architecture model whereby everything is tightly integrated around the Cisco Unified Communications Manager platform. with the IM&P server (former Presence Server) now a component of CUCM, the new Jabber softclient (new version of jabber fills now the gap between traditional telephony and softclient features), Cisco Expressway (features such as MRA & JabberGuest, B2B, Lync Interop) Cisco Conductor (resource management etc), There is now also a more defined strategy for on-prem, cloud and hybrid with finally with the icing on the cake, the constantly and rapidly evolving Cisco Spark

all of which in due time I will aim to cover in more details 🙂

 

IOS Toll Fraud Prevention

I was recently configuring a VG202 (yeah that little cutie) for a customer and when making inbound test calls they were failing:-

I checked the configuration and there was no reason for the call to fail, did a debug voip ccapi inout and saw the following error:-

>>>>CCAPI handed cid 19 with tag 2000 to app “_ManagedAppProcess_TOLLFRAUD_AP
*Mar  9 02:41:02.915: //19/0050FCDF0800/CCAPI/ccCallDisconnect:
Cause Value=21, Tag=0x0, Call Entry(Previous Disconnect Cause=0, Disconnect C
ause=0)

Hmm.. i thought this was only applicable to IOS 15.X and above but seems like i was wrong, looks like this 12.4(20r)YA1 has Toll Fraud mechanism

The following command <voice iec syslog>will also help you get toll fraud debugs;

*Mar  9 02:36:17.163: %VOICE_IEC-3-GW: Application Framework Core: Internal Erro
r (Toll fraud call rejected): IEC=1.1.228.3.31.0 on callID 13
*Mar  9 02:36:17.283: %VOICE_IEC-3-GW: Application Framework Core: Internal Erro
r (Toll fraud call rejected): IEC=1.1.228.3.31.0 on callID 14

you can either create a trusted ip access or disable it totally; see Toll-Fraud Prevention Feature in IOS Release 15.1(2)T for more information

What is Presence & Cisco Unified Presence Server

Presence is the ability to show the status of a user; idle/busy/away, devices they are contactable on and how best to contact them. Simply put it “is the aggregation point of availability represented by a single or multiple devices associated with a user account that can be monitored by users”

At the core, presence is a person’s willingness and ability to communicate utilising all network connected mediums available to them to make them more contactable and productive.

Available mediums are integrations to conferencing resources, calendar, email & IM clients. Utilising these one can make an informed decision as to what maybe the best method of contacting a user. On the other end, users can set their status and also enable features such as SNR that allows them to advertise a single number and be contactable on multiple devices; when a user is called on a deskphone; their home phone/cell phone can simultaneously ring and when connected the call can be transferred to the deskphone/remote phone without any or very little media interruption. Users can also have voice messages delivered to their email inbox, can visually chose what message they wish to listen to and so on.

Cisco UC clients consists of the following;
Cisco IP Communicator (CICP). A windows application that offers softphone capabilities, the same as a deskphone would

Cisco UC Integration for MS Office Communicator (CUCIMOC)-  An Client service Framework (CSF) application that provides services such as softphone, mid-call control, desktphone control, IM

Cisco Unified Mobile Communicator (CUMC)- an application for mobile phones and smartphones that allows users to place/receive calls, access corporate directory, view user status, access voicemails, utilise MeetingPlace and Webex conferencing etc.

Cisco Unified Personal Communicator (CUPC) – this provides integration and a single interface to a wide variety of services such as call control, video, im, web conferencing, voicemail. it also allows you the ability to Click-to-dial from MS Excel/Outlook/Word and even the web

Cisco unified Video Advantage (CUVA)- adds video functionality to an ip phone by utilisng deskphones or CIPC utilising existing network infrastructure.

Cisco Presence Server
Cisco Unified Presence Server (CUPS) is the core component of the Cisco Presence solution, it is a separate product integrates directly into CUCM as an extended application.  As outlined in RFC 2778 there are 3 basic components to a presence solution;

  • [Collect Status] Presence Service: This service aggregates and distributes presence information between clients
  • [Publish Status] Presentities: Clients that provide presence information to the presence service to be stored and delivered. Presentities publish their service to the presence server using a PUBLISH or REGISTER message for SIP/SIMPLE Clients or XML Presence Stanza for XMPP clients. It can be DN or SIP uniform resource identifier (URI) that resides outside or within a cluster
  • [Consume Information] Watchers: these are Presence clients that receive presence information from the presence service. They do this by
    • Fetching: retrieves current presence information from presence service about a presentity; done upon user request
    • Subscribing: retrieves current and future presence information from the presence service about a presentity. Provides ongoing subscription to receive status updates

Components of Cisco Unified Presence

  • Cisco IM and Presence Service
  • Unified Communications Manager (CUCM)
  • Cisco Jabber
  • Meetingplace or MeetingPlace Express
  • Unity or Unity Connection
  • Unified Video Conferencing or meeting place Express VT
  • UCCE / UCCX /CVP
  • Cisco IP Phones
  • LDAP Svr 3.0
  • Third Party Presence Server/XMPP Clients/Applications

An Illustration of Components;

CM Presence Capabilities
When a IP Phone sends a watcher request, CUCM manages the request locally and if the presentity is located on a separate CUCM cluster or CUPS it forwards the request across the SIP trunk to the external service (provided the user is in the SUBSCRIBE CSS & Presence group that allows the watcher to monitor the requested presentity).When CUCM receives a SIP NOTIFY response on thr trunk it responds to the SIP Line-side presence request by sending a SIP NOTIFY message to the watcher indicating the current status of the presence entity. The services that are natively supported on CUCM are BLF/SpeedDials and Call history logs

CM Presence with SCCP
since CUCM supports SCCP endpoints as presence watchers and there are no SCCP trunks, SCCP endpoints can request the presence status of a presentity to the CUCM by sending SCCP Messages. If the presentity resides within the same cluster CUCM responds back indicating the current status of the Presentity. If it resides outside the CUCM Cluster, CM routes a SUBSCRIBE request out a appropriate SIP trunk based on the SUBSCRIBE css, Presence Group & SIP Route Pattern. When CUCM receives a SIP NOTIFY it responds to the SCCP line-side presence request bysending SCCP messages to the presence watcher, indicating the current status of the presence watcher.

CM Presence Policy
you can create a policy in CM for users who request presence status, inorder to do this you will need to configure a CSS specifically to route SIP SUBSCRIBE messages for presence status and status of users in another group.

CM Subscribe Calling Search Space
The first thing to do is to define a SUBSCRIBE css. CM uses this to determine how to route this request  from a watcher (a phone or a Trunk) The SUBSCRIBE css is associated to the watcher and lists the partitions the watcher is allowed to ‘see’. This operates independently of normal CP routing.

This can be assigned on Devices or on a User (EM). A SUBSCRIBE with a CSS set to <None> will reject subscription messages as unknown. If a valid CSS is specified, SUBSCRIBE Messages are routed properly./

Presence Groups
The second aspect of the presence policy is presence groups. By default they are all assigned to the Standard Presence Group. A Presence group controls the destination a watcher can monitor

Cisco IM & Presence Cluster
Cisco IM and Presence Cluster consist of upto 6 server’s incl one designated as a publisher . The architecture being the same as a CUCM cluster. Within a cluster you can have a subcluster which can have upto 2 servers upto 3 clusters in a CUP Server cluster without redundancy. The CUP Server publisher uses the database of the CUCM Publisher and can support only one CUCM cluster. User assignment is done automatically using Sync Agent. Synchronisation can be anything between 5 mins for 500/1000 users upto 70 minutes for 70000 users (platform dependant) – this takes alittle longer when CUCM is integrated to CUP cluster and not CUPS Publisher

Computer Telephony Integration Quick buffer Encoding (CTI-QBE) is used between the CUCM & CUP Clusters for CTI Functionality at user level. This allows CUP Server to control phones and provide functionality such as deskphone control from a software client. LDAP integration is via the CUCM and not with the external LDAP Server. AXL/SOAP on CUPS is used to provide database synchronisation from the CUCM Cluster.

Federation to other CUCM Clusters and MS Lync/OCS Server is done via the same CUP Server.
