Call Transfer issue, No audio and no voice

Call Transfer issue, No audio and no voice

Call Transfer issue, No audio and no voice

(OP)
Hi

we have Nortel CS1000E 7.6 system which is integrated with CISCO CUCM via Session manager SIP Trunk.
I have created DSC for CISCO Extn And routing has been done in Session manager.
The integration is successful Nortel Phone is able to call Cisco and Vice versa happening.
But is issue is with call transfer
eg Nortel IP Phone Extn 50133 called to Cisco Extn 50003 Voice is OK
Cisco Extn 50003 Transfer The same call to Another Nortel IP phone Extn 50572
After the call getting transferred there is no Audio/Blank between both Nortel IP Extn 50133 and 50572.

Here is the DCH Configure, please suggest what need to be done at Avaya end or CISCO end.

RE: Call Transfer issue, No audio and no voice

I'm not sure if you need to have "TRMB" set to "YES" against the routes RDB in LD 16.?

RE: Call Transfer issue, No audio and no voice

The only other thing I can think of is if there is another setting in "RCAP" that needs to be looked at.

RE: Call Transfer issue, No audio and no voice

(OP)
Please suggest what option I could enable for this issue as currently SIP DCH has RCAP ND2 MWI.

And all external calls are going through with this DCH, we have to take downtime for any changes in SIP DCH.

As we are facing issue only while call getting transferred from CISCO Extn.

Nortel calls---to CISCO-----Transferred call-----to Nortel ===> No audio/Blank

Nortel to Nortel and CISCO to CISCO the issue is not happening.

Also please suggest how we can disable/enable the SIP DCH for making any changes.

RE: Call Transfer issue, No audio and no voice

We have the same configuration active.
In contrast to you, we do not use standard in the routing script ( SIGO = STD) and in the D channel RCAP = TAT ( anti-trombon )
We operate the trunks with wnk/wnk instead of IMM/IMM .
most often such problems occur in connection with several features.
A standard SIP trunk is installed in the Cisco system.
I have attached a few more screenshuts .
Good luck

Thanks for your revert.

I will try to add RCAP to TAT.

But for that we need to disable SIP DCH,

Please suggest me how to disable the SIP DCH, will take the downtime accordingly.
