[asterisk-users] One way Speech issue - only in PAP2T to SIP device attached to Asterisk but not PAP2T to Voip service provider

[Shaun]

Hi All, 

This is puzzling me greatly. 

The setup: PAP2T over ADSL registers to Asterisk 1.4?using SIP. Attached to Asterisk are SIP clients. Codec throughout G729 (only have 1 license on Asterisk server loaded though). When calling the SIP clients from PAP2T I can't hear them but they can hear me. 
 
If I call from PAP2T through Asterisk using?IAX2 to a VOIP provider there is speach in both directions! 
 
Any suggestions? 
 
Thanks Shaun
