How can we trunk out from two pbxnsip systems

[gotvoip]

Can you route from trunk to trunk. A customer wants to have two pbx’s tied together in 2 countries and be able to dial out to locale numbers. So PBX-A has a trunk set up to PBX-b and P to A. They would like to dial ext numbers on PBX-b(no problem) and would also like dial a 6 plus 10 digits for local numbers this is where I need some help.

The easiest way to do this is if you create a sip tie trunk but the users will have to dial twice. On each pbx create a trunk and on the other system create an extension that the other trunk registers to and map it to an AA. So if you create trunk 1 on system 1 and it maps to extension 2, they can dial 2 locally and it will go out the trunk to the other system and hit the autoattendant where they can three digit dial or dial any outbound numbers via the dial plan since they will look like an extension of that system and visa versa. In order to work with exchange 2007 UM we had to add the capablility to come in one trunk and then go to the exchange server trunk so it is possible to do it that was well but it is more complicated in my mind! Maybe someone else can answer that part.

I have the trunks setup but when you hit the auto attendant it will not allow you to dial a 10 digit number. You get a recording saying that the number is a invalid ext.

Do you have the dial plan setup correctly to route the call out that trunk? Something like below so if you press 9 it sends out that trunk. A snippet of the log would be nice.
