Re: voip over wirless lan it is possilbe ,i mean over radio freq

VoIP is just an ip packet so yes if you can transport data properly over your wireless area, then you can do so with voip as well. What may cause a very serious problem is the DELAY; wireless networks are still very slow and as far as voip is concerned, 150msec RTT is ideally required and you can still go up to possibly 300-350msec RTT but anything above that will cause degradation of your voice quality. So keep those mind.

Furthermore, a 64k link is very small , you have to do fragmentation so voice is not additionally delayed, and you can only do about 4 or 5 calls IF you turn on cRTP (header compression).

Hope this helps. All the best.
