The endpoint is either not receiving or is ignoring the response from Asterisk.

saadat · March 13, 2020, 2:20pm

Hi jcolp,
What endpoint are you talking about? My asterisk server is on aws.
Are you talking about my local internet?

jcolp · March 13, 2020, 2:21pm

It would be Zoiper. Asterisk is sending a response to the call attempt, but Zoiper is not receiving it. It keeps sending the same call attempt over and over.

saadat · March 13, 2020, 2:22pm

I get this error in asterisk logs

ERROR[6001]: chan_sip.c:17944 register_verify: 'TCP' is not a valid transport for '21003'. we only use 'UDP,WS'! ending call.
[Mar 13 14:21:05] NOTICE[6001]: chan_sip.c:28959 handle_request_register: Registration from '<sip:21003@3.13.25.206;transport=TCP>' failed for '203.128.18.19:48373' - Device not configured to use this transport type

jcolp · March 13, 2020, 2:27pm

You seem to have switched it to using TCP in Zoiper, without allowing it in Asterisk. “tcp” has to be added as a transport in the SIP peer/friend/user.

saadat · March 13, 2020, 2:28pm

I didn’t do anything in zoiper. This came after some tries.

jcolp · March 13, 2020, 2:29pm

It, or something else, tried over TCP.

saadat · March 13, 2020, 2:30pm

No. Every time i hit using register now using zoiper, the above error comes

jcolp · March 13, 2020, 2:31pm

Then you’ll need to enable tcp as an allowed transport on it.

saadat · March 13, 2020, 2:32pm

Does it have any disadvantage? We were testing with udp before. I don’t know why it isn’t detecting udp now.

jcolp · March 13, 2020, 2:32pm

No, but if UDP packets were not getting through previously I would be concerned that media would not flow since RTP uses UDP.

saadat · March 13, 2020, 2:35pm

That mean issue is with zoiper not connecting over udp.

jcolp · March 13, 2020, 2:37pm

When it was communicating using UDP the packets that Asterisk sent were seemingly never received by it. It’s trying TCP now, but I would be worried that when Asterisk tries to send media which also uses UDP it would not reach Zoiper.

saadat · March 13, 2020, 2:44pm

Yeah,that’s a big problem.
