Hi all, I'm using following software and equipment and I have very strange behavior: Asterisk CVS-NHEAD-05/30/05-16:42:41 H323 gatekeeper - GnuGK 2.2.2 IAX2 client - Firefly 1.9.8 build 3945 H323 client - SJPhone Build 1.50.271d H323 gateway - Welltech Wellgate 3504A When I dial from Firefly (IAX2) -> SJPhone (H323) everything works as expected. When I dial from SJPhone (H323) -> Firefly (IAX2) everything works as expected. When I dial from Firefly (IAX2) -> Wellgate 3504A (H323) phone rings... I pick up... and from Firefly side ringing indication continues... no communication When I dial from Wellgate 3504A (H323) -> Firefly (IAX2) Firefly rings... i pick up... from 3504A side i can hear the voice ... but Firefly continue ringing Does anyone experienced something similar. Any help will be appreciated. Here is dump from asterisk CLI with H323 debug and IAX2 debug on.
