[Asterisk-Users] SIP Connection to a Cisco AS5xxx gateway

[Emilio Panighetti]

Hello,

Does anybody have any experience connecting Asterisk to a Cisco gateway?
I'm trying to terminate calls into this gateway, and then route 
incoming DID numbers from the gateway into Asterisk.
So far, Asterisk sends the call to the gateway, and it connects the 
call, but there's no audio. I'm using the Cisco gateway with IOS 
12.3.10T, connecting as SIP, no registration, and as clients I tried 
different SIP Phones including Cisco ATA (which connects to the gateway 
just fine without using asterisk), Gandstream ATA and the console. They 
all communicate to each other through SIP, but not to the Cisco 
gateway. I'm using g.711uLaw as the codec to talk to the gateway.

Thanks,
E.
