Hi,
I´m currently setup a Cisco 2821 as ISDN gw for for using with asterisk and some 7960 phones. Now , after some trial and error finding the right command syntax for configuring the voice services(Cisco why not release some docs about the current IOS release 12.3T(11) if you change half of the voice commands from the last rel.?), i got it up and working. Now I can dial in, using fax-relay, dial out but it seems that VAD is still used on outgoing connections even if i had disabled everythere an can(2821, asterisk, 7960). Also a "show call active voice" shows that VAD is disabled but it is still active as i can hear this silly chopping sound and, if there is silence, the RX-counter from the 7960 does almost stop. But this is only on outgoing connections. On incomming, it seems to be disabled.
I also take a look at the SIP communications between asterisk and the 2821 but, even there, i cannot find any packet where SilenceSupp is anything else than off. As there is a switch between * and the router, i cannot check the communication from the IP phones to the 2821 after the connection is established.
Does somebody have an idea what´s going on?
Regards
Michael.
