So, I have been asked to implement two asterisk boxes at two different offices using different ISPs, etc... so I can't count on the connectivity to be 100%.
I have previously setup very basic SIP trunks between the offices (eg. Ext 55xx is one office group and 44xx is the other office group... so you can call extensions in either office, inbound DID calls in at one office, can reach an extension in another office, etc...) In every case so far, the need to do this has been minimal but has worked perfectly fine for the situation. In this case however, it appears that DID number will be at one office... and then passed to an extension (possibly at the other office). The call volume is high enough that I am wondering if there is a way to actually pass off the call to the remote asterisk box (and pass the SIP connection to the DID provider along with it) so that the original receiving server is eliminated from the packet route. Basically introduce the two with a handshake and walk away. Can this be done easily? I imagine this is dependent on the DID provider? Any hints as to what I should at? Their existing system is PBX in a Flash and Unlimitel trunks. Regards, Chuck
