Solved Trouble setting up Telnyx SIP Trunk

[SOTASOTA]

I have gone through all the guides, and tried setting up Telnyx SIP trunks to my profile.
The trunks simply will not register.






Help please!

Thanks again for all your help. If you don't mind me asking, which PBXs do you use?

I am now looking seriously at Yeastar P-Series. I setup the Telnyx trunk and it registered right away. Yeastar offers better options for us than 3CX, so I might just focus on the Yeastar since they will probably be the one I will stick with.

We use only 3CX. We tried them all and nothing was as simple and reliable as 3CX. We also tried Yeastar but felt it lacked a lot of integration possibilities for us, I know it is better now but still. We're also not fan of getting hundreds of DMs per year from them trying to sell us their thing. Also, their pricing is different, remember that!

Like I said, it usually works perfectly with 3CX as well, without issues.

I offered to assist but since you seem decided on just not using 3CX, I am not sure what more I can do.

 

[SOTASOTA]

OK...I appreciate and trust your experience with 3CX! I was just getting frustrated and needed to move forward.
I am open to to your assistance...much thanks! I can telephone you if you wish?

[SOTASOTA]

OK...I did that.

 

[SOTASOTA]

Successfully set up Telnyx SIP Trunk in 3CX V18 after 4 days of working.

Mine was also not registering by following Telnyx instructions but after using the 3CX Default Telnyx "Worldwide" template it's registered.

Note: Whitelist your 3cx Static IP from Telnyx support.

 

[SOTASOTA]

Thanks Rashid. I also tried that to no avail. Not sure how to do any whitelisting! I am logged into the 3CX portal. System is not on my local server.

Thanks Yiannish for offering your support! I am OK with you joining in! I will leave the admin to

@SOTASOTA It's my pleasure assisting. You can request Telnyx support to whitelist the IP through chat box or email. Hopefully, this resolves your issue.

We'll check that this afternoon!

@SOTASOTA It's my pleasure assisting. You can request Telnyx support to whitelist the IP through chat box or email. Hopefully, this resolves your issue.

Or via the My Account section also.

I thought that was the root of this. I reached out to Telnyx support and Telnyx responded by saying:
"Separately, we have whitelisted the IP addresses you have provided and ask that you re-test and make sure that you specify sip-anycast1.telnyx.com as the new registrar/host/domain in 3CX. If the issue persists, does 3CX logging provide verbose logging on why the SIP REGISTER was considered a failure?"

Is there a logging feature?

Hi,

Open Telnyx Portal
https://portal.telnyx.com

On the top right corner click on "My Account"

Scroll down to Access Control IP's and add Your 3cx Server IP

After these steps the SIP gets registered if not

Ping sip.telnyx.com

and add the IP shown on cmd to 3cx whitelist.

yes, there is a verbose log feature but this is just an IP whitelist issue.

The best solution is to create the SIP Trunk from scratch by selecting a new SIP Trunk from 3CX country Worldwide

All the settings must be the default

Just add the Username password from Telnyx and finish.

Ping will show the remote IP, not the PBX one.

That's what he did mate.

 

[SOTASOTA]

OK, I added all the IPs on the 3CX system to Telnyx. No joy.
ping Telynx and got 192.76.120.10
Not sure how to whitelist this?

 

[SOTASOTA]

And yes, I tried every template I could find and changed every parameter I could find. I have been at this for over 24 hours (not in a row )
