6. Your problem:

I need to make trunk to trunk calls, I mean:

I have two Brekeke PBX two diferentes sites.
I need from one UA of the PBX A make a call to PBX B so the call go out to a SIP trunk connected to my ITSP of the site B, also knowed as Trunk To Trunk Calls.

It is possible, If yes, how can I to do that?

Example:

Site A has the extension 120, from extension 120 I need make one external call so this call go out thru the ITSP trunk of site B that has the outgoing prefix setting as 0.

Best Regards

Juan Acevedo

servers with PBX A and B can only go through ITSP to reach each other?
If not, you can make calls between pbx servers without going through ITSP.

Thanks:

I fact I don't make calls between PBXA y PBX B using the ITSP
My interest is to make a call from one extension af PBXA to go out the ITSP connected to PBXB

have you tried with setting up an ARS pattern-out at pbx A to send call to ITSP address when dial ing numbe is prefix 0 + DID, which is pointed to PBX B address by ITSP?
can the call be established?
what error is sent from itsp to pbx A?
