Hi, I have Asterisk setup and registered with Gossiptel but i'm only getting 1 way audio. If I call 160 (echo test) or 123 (talking clock), it makes the call but I just get silence. If I call my Gossiptel number from a pstn line, I get gossiptel -> pstn audio but not pstn -> gossiptel audio. I've got ports 5060 and the rtp ports forwarded in on the firewall and I have 3 other sip providers setup and working on the same Asterisk box - it's only Gossiptel i'm having problems with. Any ideas? Anyone had a similar problem? Anyone got it working? Here is my config snippet from sip.conf: register => USERID:PASSWORD@sip.gossiptel.com/USERID [gossiptel] type=friend username=USERID fromuser=USERID authuser=USERID secret=PASSWORD host=sip.gossiptel.com nat=yes insecure=very dtmfmode=inband canreinvite=no fromdomain=sip.gossiptel.com disallow=all allow=ilbc allow=gsm allow=ulaw allow=all Thanks --ian
