Hello, as a part of my master thesis I'm going to implement a SIP UA using PJSIP and python. I'm trying to use TLS for the communication (for every outgoing messages - REGISTER, INVITE, ...). Unfortunatly, I have the following problem: imort pjsua as pj [...] trans_cfg = pj.TransportConfig(port=5061) transport = lib.create_transport(pj.TransportType.TLS, cfg=trans_cfg) [...] returns with: python: ../src/pjsua-lib/pjsua_core.c:2010: pjsua_transport_get_info: Assertion `!"Unsupported transport"' failed. Replacing pj.TransportType.TLS with pj.TransportType.UDP or pj.TransportType.TCP it works well. I also tried to establish the TLS connection by using C and it worked too. How can I solve this problem in python? Thanks in advance. Regards, Sebastian

Maybe you need to start a TCP transport and then do something else, can't remember right now, sorry. You may want to try SIPSIMPLE SDK, a high level API written in Pyton for coding SIP clients (PJSIP based): http://sipsimpleclient.com Regards, -- Saúl Ibarra Corretgé AG Projects
