Dear all,<br />
<br />
I have following setup:<br />
ISDN GW 3241 <---H.323---> CUCM 8.6.2 <---SIP (native)---> SX20/C60<br />
<br />
Incomming and Outgoing ISDN calls are working (audio and video) but on some devices (Polycom) I have only Audio.<br />
<br />
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:<br />
ISDN GW 3241 <---H.323---> SX20/C60<br />
<br />
Please find attached capured packets on CUCM (call estabilished with SIngapure Polycom test number: 006563254856)<br />
Packet 31 (openLogicalChannel (genericVideoCapability)) and 32 (openLogicalChannelReject) are most important.<br />
<br />
Legend:<br />
22.62.22.18 - CUCM<br />
22.62.22.36 - ISDN GW 3241<br />
<br />
Thanks for any help.<br />
<br />
Cheers,<br />
Lukasz</p>
