Hi I am trying to use the ringback tone played by PABX when calling a specific extension. However, no sound is played. The pjsua application found in examples uses only a locally played tone, without tone I cannot hear any sound from the PABX. Is there a specific setting for PJSUA library that allows to play the ringtone of the PABX instead of the local one ? thanks Bogdan -------------- next part -------------- An HTML attachment was scrubbed...
