Hello I am having a problem oputting a call on hold. I am using the method: pjsua_call_set_hold(...) to put the current call on hold and it did work for one or two times. Then i used the method pjsua_call_reinvite(...) to release the call from hold. But for some reason putting the call on hold is not working anymore!!! I keep getting the following error message in the logs: * 16:16:27.347 tsx0xbd7664 Temporary failure in sending Request msg INVITE/cseq=24666 (tdta0xbd5400), will try next server. Err=171060 (Unsupported transport (PJSIP_EUNSUPTRANSPORT))* * 16:16:27.347 pjsua_core.c TX 1480 bytes Request msg INVITE/cseq=24666 (tdta0xbd5400) to UDP 94.75.247.45:5060:* Which does not make sense to me. Hope someone can point me to the right direction of debugging/solving this issue.
