Dont know if anyone found this before, but here it goes. 3CX doesnt support G729 codec right? now, i have my 3 VSP lines, they all support this codec. What i've done is, i setup all my phones and adapters to use G729 has preferred codec, not restricted to only this one thoug. Now, i managed to make calls with this codec using 3CX without any audio issues. I think that, what is happening here is, since 3CX doesnt support this codec(i get the error message from mediaserver that they couldnt find intersection codecs) 3CX redirects the connection to the phone(that supports this codec) and the connection goes through wihtout using more bandwith then the necessary. Not sure if this is working like this (the redirecting thing to my phone and adapters) but its what it seems to me, and if its really true then, its very good, since it wont take all my bandwith (if im on 3 calls at once). If anyone could try this aswell to see if it is really like this (just to confirm) it would be nice. Cheers P.S. - One question, can i send my ID with voipstunt? Like i wanna send a number through Voipstunt. for what i've seen on voipstunt its possible, just dont know how to, on 3CX.
