[Asterisk-Users] Always Ringing

[VoIP Newbie]

Hi all,

I am using chan_h323 from Asterisk CVS to interconnect with GNUGK
v2.2.2. Then I made call from a H323 EP, thru GNUGK, to SIP EP on
Asterisk. However, I only heard ringing when the call was answered on
SIP side. Below is the debug from chan_h323. Any help is welcome.
Thanks.
