I have a CUBE (IOS 15.2.1(T)) connecting between an MS-Lync system and a CUCM 8.6 system.
Normal calls are going through the CUBE fine. But when a Lync number is call forwarded back to CUCM, the divert call fails.
Doing a Wireshark, I can see the SIP message to setup the new call leg come into CUBE:
INVITE sip:01AAAAAAAA@172.18.1.249;user=phone SIP/2.0
FROM: "G Ross (CS)"<sip:BBBBB;phone-context=PstnGateway_172.18.1.249@acme.com;user=phone>;epid=7FD7CE0A07;tag=d88c165560
TO: <sip:AAAAAAAAAA@172.18.1.249;user=phone>
CSEQ: 27001 INVITE
CALL-ID: c6900010-58d8-43f6-b086-006f9dd8ed0c
MAX-FORWARDS: 70
VIA: SIP/2.0/TCP 172.18.3.241:59407;branch=z9hG4bK3323b06f
CONTACT: <sip:acme.com:5060;transport=Tcp;maddr=172.18.3.241;ms-opaque=cd9dc7108349c7d9>
CONTENT-LENGTH: 340
REFERRED-BY: <tel:+44CCCCCCCCC;ext=605>
SUPPORTED: 100rel
USER-AGENT: RTCC/4.0.0.0 MediationServer
CONTENT-TYPE: application/sdp
ALLOW: ACK
Allow: CANCEL,BYE,INVITE,PRACK,UPDATE
but nothing goes out to CUCM. (and so Lync times out the setup of this new call leg)
In the CUBE config, I've got:
voice service voip
sip
referto-passing
and also:
dial-peer voice 9999 voip
voice-class sip referto-passing
Any suggestions as to what to do, or where to look ?
Thanks,
GTG
