Hello,
We recently performed an upgrade from 8.61 to 8.62. Since the upgrade, incoming off-net diversion (cfwdall) to the PSTN stopped working. Here is the call flow for our setup:
PSTN caller-->AVAYA CM SIP TLS-->AVAY SES SIP-->CUCM-->CFWDALL-->Avaya SES SIP TLS-->Avaya CM-->PSTN.
Calling from an internal SCCP Phone to another SCCP with CFWDall works fine. The problem is when a caller from the PSTN calls an SCCP phone with CFWDALL to PSTN cell phone the call fails at the Avaya with "407 Proxy Authentication required". I believe this because the FROM header has the domain of the Avaya and not the IP Address of CUCM.
Prior to the upgrade, the Diversion SIP INVITE FROM header has the ip address of the CUCM server:
INVITE sip:94445551212@10.42.51.34:5060 SIP/2.0
Via: SIP/2.0/TCP 10.170.99.12:5060;branch=z9hG4bK422a01feef6dc
From: <sip:4445551234@10.170.99.12>;tag=315634~10e1eefb-2ebd-4fac-98ce-62a72a88c661-62310000
To: <sip:94445551212@10.42.51.34>
Post upgrade the CUCM server is sending the originating sip domain from the Avaya SES:
INVITE 94445551212@10.42.51.34:5060 SIP/2.0
Via: SIP/2.0/TCP 10.170.99.12:5060;branch=z9hG4bK4214471ca38c3
From: <sip:4445551234@sip.avayadomain.com>;tag=315423~10e1eefb-2ebd-4fac-98ce-62a72a88c661-62309759
To: <sip:94445551212@10.42.51.34>
I think this can be addressed with a SIP normalization script to replace the sip.avayadomain.com with the IP Address of the CUCM server sending the INVITE. I have yet have to implement a SIP normalization script and would like some expert help in creating the normalization script.
Thanks.
