[cisco-voip] ISDN calls trought GW 3241 from CUCM

[Łukasz Pilatowski]

	Dear all,

	

	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.

	

	Legend:

	22.62.22.18 - CUCM

	22.62.22.36 - ISDN GW 3241

	

	Thanks for any help.

	

	Cheers,

	Lukasz
