[asterisk-users] Multiple protocols for transport in PJSIP

[Carlos Chavez]

Is it possible to use serveral protocols for a single transport
section in pjsip.con? In sip.conf you could use transport=udp,ws,wss so
you cound use webrtc along with your phones but if I try:

[transport-udp]
type=transport
protocol=udp,ws,wss
bind=0.0.0.0

I get an error that transport-udp is not found. Do I need a
dedicated interface for WebRTC?

[Feb 15 12:42:10] ERROR[3308]: res_pjsip.c:2432
sip_get_tpselector_from_endpoint: Unable to retrieve PJSIP transport
'transport-udp' for endpoint '4000'

No, each transport is for a specific protocol. You can have multiple.

And how is this accomplished? If I put an extra transport section in
pjsip.conf it does not show with "pjsip show transports", I only see the
first. I also get an error in the log file:

Without the precise configuration it's hard to answer, but in the case
of the Websocket one you don't need to create a transport. Provided
chan_sip doesn't have it enabled and loaded first then it will be
available when res_pjsip_transport_websocket is loaded.

Ok, thank you. So, if for example I have my main transport
configured as:

[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0
local_net=192.168.2.0/24
external_media_address=XXX.XXX.XXX.XXX
external_signaling_address=XXX.XXX.XXX.XXX

Does that mean that I do not have to specify another transport
section with transport=ws?

Correct, you don't.
