First let me apologise for posting in English but my German is not good enough to make up a sensible posting... I have been asked to proide a client with a wireless network for their new offices, so far no problem, done it lots of times before. But now they have asked me to look into VOIP over this wireless network. It has to be able to do the following; 1) Make calls from handset to handset (obviuosly). 2) Make calls from a handset on the internal network to an outside number on the regular telephone network. 3) Receive calls from the regular phone network. 4) Able to route calls to the correct extension. 5) call queing etc. Basically they are looking at a 15K bill (minimum) to get a similar setup as what they have in their current offices and want to explore some alternatives. I've been pointed to this forum by a few people and was wondering if anyone here can give me some pointers. One of the things I have been recommended to look into is the Asterisk servers..
