PJSUA2 doesn't work over TCP

[niknaz87]

Describe the bug Trying to make pjsua2_demo work over TCP connection. Code:

    EpConfig ep_cfg;
    ep.libInit( ep_cfg );

    // Create transport
    TransportConfig tcfg;
    tcfg.port = 5060;
    ep.transportCreate(PJSIP_TRANSPORT_UDP, tcfg);

To Reproduce Make changes to pjsua2_demo.c to work over TCP. Code: ep.transportCreate(PJSIP_TRANSPORT_UDP, tcfg);

Try to register with the modified code.

Expected behavior Registration should be successful over TCP

Have you added ";transport=tcp" at the end of the SIP URL? for example: "sip:[email protected];transport=tcp"

This works for me as a workaround. Is this a prefered way how to make other than UDP (which is default) work? I need to append also this string to the outgoing call URI when I configure with userless account.

BTW, I do not see this documented in https://www.pjsip.org/docs/book-latest/html/account.html#creating-account When I checked also some example codes, it required only ep.transportCreate(...) https://github.com/pjsip/pjproject/blob/master/pjsip-apps/src/samples/pjsua2_demo.cpp#L438
