[cisco-voip] Single Number Reach, CallerID and Avaya

[Ryan Ratliff]

Assuming that 61234 is defined as a remote destination for 61010 then this is part of how SNR works.  Any call from a remote destination shows as the internal DN/name.

What is your problem for this behavior?  If the two phones aren't owned by the same person then this isn't what SNR is intended to be used for.  If they are, what does the number matter when both phones will ring when the IP phone is called?

    Greetings.

    I hope this description makes some sense.  The DIDs have been
changed to protect the guilty.  ;)

System description:

CUCM 7.1.3 with a 2921 as a MGCP gatekeeper

Avaya CM running CM 5.2.1 SP#4

The two systems are interconnected using a QSIG trunk.

All PSTN trunks are connected to the Avaya.  The University has two DID
blocks.  We'll call them 213666XXXX and 213777[0-2]XXX.  I've allocated
21377727XX to CUCM.

Stations on the Avaya system can call stations on the Cisco system and
vice-versa using 5-digit extensions.  I have both systems exchanging
5-digit extensions to make inter-system calls.  Off-net calls work as
well.  I have CUCM prefixing 21377 via a Calling Party Transform before
submitting the call to the trunk for off-net calls.  I do this at the
Route Pattern for off-net calls.

I've been looking at Single Number Reach and it seems to mostly work.
However, when a call from an Avaya station calls a station on CUCM, the
resulting Calling Party number is incorrect.  For example, if a call is
made from Avaya station 61234 to a CUCM station, the Calling Party
number that gets displayed on the cell phone is 213-776-1010, rather
than 213-666-1234.  Recall that I am inserting 21377 on off-net calls.

Is there a way to alter this behavior on the Cisco?  Anyone have any
suggestions as to where to look for a solution?

    Thanks!
