[cisco-nas] RE: Cisco H.323 standard compliant or not

[Najeeb Haddad]

Based on H.323 standard (check H.225) SETUP ACK is an OPTIONAL message for
both transmit and receive. I attached the spec for you in a separate email
so you can check Table 4 (H.225 Usage of Q931 messages).

Subject: Cisco H.323 standard compliant or not

Hi all,
We have been discoverd with testing with 3rd PTY VoIP GW that Cisco VoIP GW
implementation of H.323 stack in not standard compliant. We test several
images from 12.1. to 12.2. and find out that Cisco VoIP GWs does NOT send
for H.323 Setup message response H.323 setup acknowledge. Based on the H.323
standard every device must send H.323 SETUP ACK when it receives H.323
SETUP. Anyone has experience this behaviour too.

Best regards,
Tomaz
