Hi, I have a problem with outgoing calls with linphone. linphone can successfully register with the sip server, and can also receive incomming calls. But when initiating outgoing calls I receive the following error from the sip server:
503 Service Unavailable Q.850 ;cause=42 ;text="3" Some more information: - the SIP provider is arcor (xxxxx.sip.arcor.de now owned by Vodafone) - I am using Linphone 3.8.5 - I was able to do outgoing calls using another VoIP client (sflphone) - I get the same error on my smartphone using Linphone for android (Linphone 2.4.1) - on Android I can successfully do outgoing calls with a different client (CSipSimple) linphone is doing something differently compared to other clients. Do you have any idea what this could be? Can this be a configuration issue? Or a difference in the implementation of the sip protocol? I have already tried to compare the sip traffic with what happens with sflphone (using wireshark), but didn't find a significant difference in the INVITE request. But maybe I don't know what to look for ... Hope someone can help, Best regards, Frank. _______________________________________________ Linphone-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/linphone-users
