I can see your dial-peer 102 pointing to port 5070 of your ITSP SBC but the OPTIONS sip message coming from port 10.91.52.38:5060. You might need to change the destination port on the dial-peer

Hi

as per the provider here is their test configuration for express talk softphone. We should use port 5070.

Hi,

From the logs it is clear that you are sending INVITE To ITSP but you are not receiving any response from them. Either they are sending the response but your CUBE is not receiving it. Please see below screenshot:

In the outgoing dial peer 102 you have configured session target with port 5070. Is ITSP requesting you to send the signaling on port 5070 or 5060?

Also, please change below configuration on your CUBE Router:

voice service voip
 mode border-element 
 sip
  no bind control source-interface GigabitEthernet0/0/0
  no bind media source-interface GigabitEthernet0/0/0
  no session transport tcp

Hi 

Still the same. as per provider we should use port 5070. Below is the test config for express talk softphone.

Attached file is the debug. Thank you.

Hi,

Under CUCM SIP Trunk pointing to CUBE router, change the destination SIP Address to 192.168.3.8. At present you are sending INVITE packets from CUCM to external IP Address (i.e. 10.05.82.162) of CUBE Router. This will not work with your current dial-peer configuration. Also, please change below configuration on your CUBE Router:

voice service voip
 mode border-element 
 sip
  no bind control source-interface GigabitEthernet0/0/0
  no bind media source-interface GigabitEthernet0/0/0
  no session transport tcp
!

Hi Vaijanath

 

Already changed the config in the router and destination address in cucm. Still the same cannot make calls.
Attached file is debug. Thank you so much.

Hi,

Everything seems to be good on your side. Do you have firewall or ACL or any other device between CUBE and ITSP that is blocking SIP traffic from ITSP. I do not see any traffic coming from ITSP. For incoming calls, do you see any incoming traffic on your CUBE Router?

Hi,

 

There is no firewall between CUBE and ITSP. We already checked it on fortigate but no traffic coming from the router.
Attached is incoming debug ccsip messages. There is a mismatch in Min-SE?

Hi All

 

Incoming is now working. After changing the value of min-see = 600 and in

dial-peer voice 201 voip
description ** Outgoing From VG to CUCM **

voice-class sip bind control source-interface GigabitEthernet0/0/0 (it was Port-channel1)
voice-class sip bind media source-interface GigabitEthernet0/0/0 (it was Port-channel1)


Outgoing still not working

Attached files are debugs of outgoing and incoming that might help you. Thank you.

 

Hi,

It is good that incoming calls are working. Can you post following debug logs for outgoing calls:

  • debug ccsip calls
  • debug ccsip error
  • debug ccsip messages
  • debug ccsip events

Also, when you are testing outgoing calls, is it possible to collect logs on your service provider side to see what they are getting and what they are sending?
