Sorry in advance but VOIP is pretty new to me - so if there is a better place to look or post, please do direct me there.
Our company has a main office with about 160 people. We already use a pretty old but entirely satisfactory Telrad PBX. We also have several branch offices. These have far fewer staff - perhaps 10 per office.
We have been trialing Skype between the main office and branch offices - however this is a bit of a messy solution, not only in infrastructure terms, but also in that the normal telephone can ring while somebody is already using Skype.
What we would like to do is to set up a server (Asterix seems to be the one to go for), tied into our internet connection, then with several connections to the existing PBX. The branch offices could then continue to use soft-phones, connecting directly to our server. Ideally, this would allow the branch offices full access to our internal extensions and our internal users to be able simply to dial either an extension or a preprogrammed “speed dial” number on their regular Telrad handsets in order to access the branch office users.
Most FAQs and support docs I have seen either work on the basis that the Asterix server will be the sole PBX (where I want it to integrate with an existing PBX). Or, they assume that a VOIP providor will be used - we eould rather have the branch offices connect directly to us (from a strictly financial point of view - although would this potentially cause latency issues?).
Apologies for the rather rambling post - Does this sound possible, and can anybody give me any pointers as to where to start?
Thanks In Advance,
