Not sure if this is Axon, Express Talk, or even my VoIP Provider's fault - but for some reason if I hold a call, some odd music plays for the caller (this is NOT the hold music I have set on ET or Axon) and then after 5-6 seconds, the call is dropped. Playing around with the options has lead to some equally weird situations such as hold working, but not being able to speak/transmit after resuming and hold working but not being able to resume at all.
Most everything else seems fine. Audio is bidirectional, and of good quality.
Running Axon 2.0 and ET 3.06 (problem also occured on Axon 1.31). Axon on a W2K3 Server box @ a remote location. ET Running on a PC behind a NAT - but then, why should NAT be the problem if the line works fine otherwise ? VoIP provider is aql.
On a side note : How come VoIP seems to need to make a notification of 'hold' status... surely it would make more sense to mute the mic, and stream audio down the same channel without messing with the fragile SIP protocol ?
Thanks in advance.
