Asterisk 12 can't Dial to WS Peers

navaismo · December 19, 2013, 6:27pm

Hi, using Asterisk 12 i can’t communicate with peers using the websocket dialing from ws to sip works as expected, dialing from sip to ws can’t locate the peer and dialing from ws to ws is failing too.

Here is the dialplan:

[ Context 'phones' created by 'pbx_config' ] '_15XXX' => 1. Dial(PJSIP/${EXTEN:1}) [pbx_config] 2. Hangup() [pbx_config] '_5XXX' => 1. Dial(${PJSIP_DIAL_CONTACTS(${EXTEN})}) [pbx_config] 2. Hangup() [pbx_config]

The Contact List of the peers:

 pjsip show endpoint 5001
Endpoint 5001:
AOR 5001:
	Contact sip:5001@10.0.1.102:48116;transport=ws;rtcweb-breaker=no:
		available = yes
		RTT = 114700 microseconds

pjsip show endpoint 5000
Endpoint 5000:
AOR 5000:
	Contact sip:5000@10.0.1.110:5063:
		available = yes
		RTT = 414624 microseconds

The result of dialing from SIP to WS

I’m not familiar with the web sockets support, but the error is “no route to destination” which either means that the host OS doesn’t know how to send to 10.0.1.102, or there is a syntax error causing the wrong address to be parsed from the string.

(I suppose web sockets could involve using a proxy that is off your network, as well.)

If I removed my transport for the peer then it can be reached, but then it can’t dial out so I guess something is wrong with the transport that I have made.
