[OpenSIPS-Users] How to implement a SIP Trunk in between two SIP servers.

[steven chew]

Hi Bogdan,

Thanks for your reply.


Your script is very useful for calling between two opensips servers which I
have tested.

However, I don't know how to configure on CUCM 7.0 which I am using.

At the moment, CUCM 7.0 is using Web Config via the Web Browser.

Can you let me know how to configure on CUCM 7.0?

I will appreciate very much if you give some instructions for  configuring
SIP Trunk on CUCM7.0


Thanks
Kind regards,
Steven,
