ISDN calls trought GW 3241 from CUCM
I have following setup:
ISDN GW 3241 <---H.323---> CUCM 8.6.2 <---SIP (native)---> SX20/C60
Incomming and Outgoing ISDN calls are working (audio and video) but on some
devices (Polycom) I have only Audio.
When I bypass CUCM and register codec directly to ISDN GW 3241 (build in
gatekeeper) tought H.323 audio and video works to/from Polycom:
ISDN GW 3241 <---H.323---> SX20/C60
Please find attached capured packets on CUCM (call estabilished with
SIngapure Polycom test number: 006563254856)
Packet 31 (openLogicalChannel (genericVideoCapability)) and 32
(openLogicalChannelReject) are most important.
220.127.116.11 - CUCM
18.104.22.168 - ISDN GW 3241
Thanks for any help.
