Configuring IAD2431 to talk SIP with Asterisk PBX

[sbennett1298]

Hello,

I am trying to use an IAD2431 as an ATA to connect 8 POTS phones to Asterisk PBX. (Through a NAT)

I am at IOS 12.4 and I am trying to use the SIP protocol.

Can anyone show me config files for the IAD and for Asterisk that would make this work?

I tried using sip-ua to register to Asterisk as username "iad2431b".

It appears all 8 of my POTs peers are trying and failing to register to Asterisk.

Any ideas what I'm doing wrong?

After adding credentials to the pots dial peer my pots phones can now register to SIP servers and make and receive calls to SIPendpoints but audio is only one way. I removed the NAT so NAT is not an issue now. (There is no longer a NAT in between)

I think it might be a codec issue.

Codecs cannot be added to a pots dial peer so how does a pots dial peer negotiate a codec when calling a sip endpoint? Can codec be specified globally someplace?

The reason I suspect the codec is because when I look at the sip debug output I see

no rtp port number in the m= line and there are no a= lines after the m= lines.
