Solved Issue with Telnyx SIP Trunk in IP Based mode

[Comp4all.ca]

Hi,

I'm running Version 18 with debian 10.
I moved to Telnyx and ever since I have problem.
I'm trying to connect to Telnyx using the IP Based mode.

I followed all their instructions to configure the Trunk and the in and out rules.
Outgoing call are working fine, Incoming are not getting in. either I get all circutes are busy or the number is not assigned.

I checked the activity log for some reason it's says the authentication is not happening,,
10/07/2021 3:40:38 PM - [CM102001]: Authentication failed for AuthFail Recv Req REGISTER from 198.147.22.235:50305 tid=1135788042 Call-ID=1253626217-1877411480-2102152619: REGISTER sip:52.235.43.81 SIP/2.0 Via: SIP/2.0/UDP 10.120.2.37:50305;branch=z9hG4bK1135788042;received=198.147.22.235 Max-Forwards: 70 Contact: <sip:[email protected]:50305> To: <sip:[email protected]> From: <sip:[email protected]>;tag=739346549 Call-ID: 1253626217-1877411480-2102152619 CSeq: 2 REGISTER Proxy-Authorization: Digest username="761",uri="sip:52.235.43.81",algorithm=MD5,realm="3CXPhoneSystem",nonce="414d5359615f4d3688:c5eb181187c96dad6c0988cb9b557537",response="313b854522c94bc2071dc31bf4dc64a8" User-Agent: Auerswald COMpact VoIP sofia-sip1.12.11 Content-Length: 0 ; Reason: Credentials don't match, check that authorization-ID and password match the ones in extension settings

Am I missing something?

Did anyone else had this or similar issues?

Thank you,

Hello @Comp4all.ca

Is there a reason you are not using Telnyx in the supported configuration using the authentication method which is also the supported configuration from 3CX?

Thank you for your reply @YiannisH_3CX.

I started with this configuration. I had many issues where sometimes the call is delayed when making an outgoing call. it takes a minute to get a tone and dial the number, sometimes calls drop.

I followed the manual to the letter and I noticed that Telnyx needs to be configured with 1 perpend on the outbound rule, something I didn't have before with VoIP.ms. For my PBX it doesn't work well and the call hangs for a minute before calling. it also happened to another customer of mine.

I'm not sure why this is happening as nothing changed in the office's configuration only the VoiP provider.

This is a verbose activity log I pulled right now.
It takes a minute or more to get the line for the call

I'm not sure why this is happening,
I thought the IP-based will be better for this.
https://developers.telnyx.com/docs/v2/sip-trunking/configuration-guides/3cx-v16?type=IP
Telnyx said they are supporting it but it seems 3CX isn't.

Please try not to post unfiltered data in a public forum. The file you uploaded has your FQDN IPs usernames of extensions etc. Really not safe information to share.

Having said that I did download and the file and from a quick look I do not think you followed the guide to the letter or you did and then you decided to mess with the outbound parameters of the trunk which caused more issues that it solved.

Also are you now using the trunk as IP based or authentication based?

I would recommend deleting everything and reconfiguring the trunk into 3CX with the default template and by following the guide. Switch the trunk back to authentication based and see how that goes.

I will do that and report back.

THank you,

THank you,@

I deleted everything and started from scratch. with Credentials, it works now without the 1-minute delay I had before.
Does 3cx not support the IP-Based?

Thank you,

Glad to see you got it working. We support what we test and we have not tested the IP based trunks of Telnyx. That does not mean it won't work but authentication based trunks offer more flexibility and reliability. For example we can also support TLS and SRTP with authentication based trunks but we cannot with IP based.

So to answer your question, no we do not support the Telnyx IP based trunks because we have not tested them
