i have a cisco router 2921 with voice licence and i want to configure SIP trunk with my provider.
the configuration is next:
voice service voip no ip address trusted authenticate address-hiding dtmf-interworking rtp-nte allow-connections sip to sip no supplementary-service sip moved-temporarily no supplementary-service sip refer sip voice class codec 1 codec preference 1 g711ulaw codec preference 2 g711alaw
dial-peer voice 130 voip numbering-type unknown preference 2 destination-pattern .T media forking rtp payload-type comfort-noise 13 session protocol sipv2 session target ipv4:192.168.1.2:5060 session transport udp voice-class codec 1 voice-class sip early-offer forced dtmf-relay rtp-nte sip-notify sip-kpml ip qos dscp cs5 media ip qos dscp cs4 signaling ! dial-peer voice 160 voip description +++To Asterisk+++ numbering-type unknown preference 1 destination-pattern 4951T rtp payload-type comfort-noise 13 session protocol sipv2 session target ipv4:172.16.1.1:5060 session transport udp voice-class codec 1 dtmf-relay rtp-nte sip-notify sip-kpml
i can do calls via My provider but when i try to call internall numbers, i fail. i have translation-profile configured correctly, i guess that is not hte problem.
what i discovered is that i send SIP signaling to 192.168.1.2:5060, and ISP accests and calls work, but when the Provider initiate SIP session, he initiate with source Port 5062, and my router does not ceate incomming leg:
*May 5 16:06:58.788: //1393/3331D6519C88/SIP/Error/act_recd_invite_send_msg_failure: Send Error to 192.168.1.2:5062 for transport UDP *May 5 16:06:58.788: //-1/xxxxxxxxxxxx/SIP/Error/sipSPIGetContentQSIG: No Inbound Container Created !!!
can somebody help me with this issue? can i change the dialpeer to receive from one source port but send to 5060?

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
