Issue with NAPTR registering CompanyFlexCloud

[hofmannu]

Hi,

I'm trying to configure a Telekom CompanyFlex Cloud sip trunk with tel.t-online.de on the 3CX Version 20.0 Update 4 (Build 487 Release), but i cannot resolve the NAPTR

I noticed that the system is can not resolve the registrar and the proxys

I followed this instructions for Telekom Company Flex as well as https://www.3cx.com/docs/sip-trunk-dns-record-resolution/ .

Log:

23.12.2024 17:32:13.542	Lc:10001(@telekom Mainburg[<sip:0/UDP>])Scheduled DNS resolution in 300 sec.

23.12.2024 17:32:13.469	Unregistering Line 10001

Registrar and Proxys are set to auto-discovery

Should i configure something else outside of the sip trunk?

Any help would be apreciated !!!

Many Thanks
Uwe

Hallo Uwe,

If I were you, I would read about it in the German forum (everything on this specific topic is there) and then if there is still a need, then maybe ask there.

Have you followed the instructions?
https://www.3cx.de/docs/adminhandbuch/sip-trunks/deutsche-telekom-companyflex/

Where is 3CX running?

What kind of DNS does the 3CX use?
