CUBE: SIP to SIP Configuration

[JustForVoice_2]

Hello,

I have a SIP trunk from Service Provider. In the same time, I want to create a SIP trunk from CUCM to CUBE, so the connection will be:

CUCM>> --- SIP--- >> CUBE>> --- SIP --- > > Service Provider.

My problem is: I have to bind sip with one of the interfaces. If I use the internal one the SP company will not accept. And if I use the interface which is connected to my service provider, this interface is not routed in my network.

Could you please help?

So SIP has a flexibility to bind even with dial-peers. What you should do is to bind the dial-peer between CUCM and CUBE with internal interface, and bind the dial-peer between CUBE and SIP with the respective external interface.

Could you please tell me how I can bind the dial-peer with interface?

Under dial-peer;

voice-class sip bind control source-interface <interface>

voice-class sip bind media source-interface <interface>

Thank you :)

I'll test it and check

I tried but it did not work. it looks something related to my SIP trunk configuration

The SIP trunk status: Unknown - OPTIONS Ping not enabled

I'm trying to figure it out.

Here is a link/blog that explains in detail how to correctly configure a bind statement

You need to enable options ping in your sip profile for the status to change..
