I am in the proscess of integrating a clients remote and head office phone systems. Currenty each office has their own PBX and trunk lines. I am recommending that they put in an Asterisk server at the Head office with a WAN link to the remote office and switch to IP phones. Trunk lines at the remote site would be returned to the TELCO. External calls over the PSTN from the remote office would be routed over the WAN to the head office and through Asterisk to the PSTN trunk lines. All phones would then become extensions (both remote and head office locations). I want Person A in the remote office to dial an extension number and get Person B in the head office. What I am unsure about is if person A and Person B are both at the remote site and Asterisk PBX is at the head office, can A and B talk directly to each pther without traversing the WAN link? Has anyone done this before? What is the quality of the call if they have? Any information is useful. -------------- next part -------------- A non-text attachment was scrubbed...

[Asterisk-Users] sip phone extensions at a remote site
If you're using SIP I think what you want is canreinvite=yes which means the two remote user clients can talk directly to each other. Asterisk disappears from the loop which means no accounting. I think NAT causes problems in this scenario also.
