Issue with forming a SIP Trunk with ITSP

[Santosh Mohite]

Hi All,

I am having problem forming SIP trunk with ITSP.

CUBE is getting dhcp IP from ITSP device. CUBE is also sending SIP register request but not receiving any response from ITSP device. I am not sure what is blocking the SIP response message from ITSP. Attaching running config and debug for reference.

Thanks,

Santosh

Total guess but you have are setting a default gateway and then trying to assert a route for 0.0.0.0

The appliance isn’t going to take two default routes so you’ll need to either not set default to your ITSP if your remote peers are in the same subnet as your link, or configure some sort of routing back into your network or otherwise so it knows where to go.

Also , change your passwords for your telephony account .
