SIP EXTENSIONS

[kennedymacharia]

Hi,

I have a problem that has been bothering me for a while, I am using CME which is working fine with my sccp phones, I recently acquired cisco 9971 phones that I have registered with SIP. My problem is that the sip extensions cannot call the pstn. Please assist. here is my pstn dial peer

dial-peer voice 300 voip
 destination-pattern 9..........
 redirect ip2ip
 session protocol sipv2
 session target ipv4:10.0.0.11
 dtmf-relay rtp-nte
 no vad

debug ccsip mess

debug voip ccapi inout

Going to need debugs from those two commands.  A dial-peer by itself isn't helpful without seeing why the PSTN or the gateway is kicking back the call.

hi,

Thank you for the reply I have done this debugs but there is no output. The sip phones are calling other extensions but cant call pstn. I have attached my whole config .

Hi,

Please check following two points;

1. Add bind command for SIP under dial-peer 300

2. Add codec (or voice-class codec) under dial-peer 300 as per your service provider requirement.

If doesn't resolve, please share the output of debug ccsip messages as asked by others too.

Thanks

Vivek
