[Asterisk-Users] Problem SIP no audio just noise

Damian Minkov
Thu, 08 Jul 2004 07:00:35 -0000

I'm trying to call from XLite phone to PSTN
(I've tried this from internet and from local network the same)
The Xlite doesn't write that it is connected but receives excelent audio.
At the other end comes only noise. Some times only for a second you can
here the
caller  voice , but this was only one time :)

I saw with ethereal that UDP packets are coming and going to the
asterisk box.

Sorry for the long logs.
