I have a new SIP implementation and got the SIP information from the Service provider.
1) On the first time When we call from the desk phone to Outside (Landline/Local/Mobile/International)calls,the calling party gets the disconnect tone but the called party gets the ring. When calls connected but the call got disconnected from the called party after 20 seconds.
1) On the second time When we call from the desk phone to Outside (Landline/Local/Mobile/International)calls,the calling party gets ring back. When calls connected but the call got disconnected from the called party after 20 seconds.
Calling number : 4035 4151 (calling party)
Called number : 33217674 (called party)
I have opened a case with Service provider, they have tested by connecting the phone on the SP switch and all calls are working fine.
I have attached the logs from CUBE router/Router configuration and trunk configuration.
The major problem I see is that you didnt bind interface to sip, make following change and see if it works out fine!
voice service voip
ip address trusted list
ipv4 0.0.0.0 0.0.0.0
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
no supplementary-service sip moved-temporarily
no supplementary-service sip refer
fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none
bind control source-interface GigabitEthernet0/0/1
bind media source-interface GigabitEthernet0/0/1
Please let me know how it worked out for you!!
