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

[Joe Carroll]

In your account settings (sip.conf) for the PAP2T device, do you have reinvite enabled for one or both..  the SIP provider and/or the PAP2T device ?

check your firewall/nat settings.

If your setup will work for around 5 minutes after you have rebooted the
pap2t then you have to active the nat keep alive and nat mapping service
  in the pap2t.

DEAR STEVE,

THANKS, I  DID CHECK THEM AND THEY NEEDED TO BE ACTIVATED. THIS DOES NOT SOLVE THE PROBLE. STILL ONE WAY SPEECH WHEN CALLING PAP2T -->ASTERISK-->SIP DEVICE ATTACHED. HOWEVER PAP2T-->ASTERISK-->SIP PROVIDER WORKS FINE  AS WELL AS SIP DEVICE ATTACHED-->ASTERISK-->SIP RPOVIDER.

ANY SUGGESTIOPS WELCOME
