Hello @Hans Kuhl

Please do make sure, that you are using the latest supported firmware(you can find all the supported firmware here), that you have configured port forwarding correctly and that you have disabled SIP ALG.

Thank you, i'll be waiting for your feedback

 

[StefanW]

I can see you use sipconnect of QSC.

you MUST enter caller IDs in +49XXX format. Your calls fail when it is not in this format outbound.

wrong
<sip:[email protected]:5060>
correct
<sip:[email protected]:5060>

here more info for your provider:
https://www.qsc.de/fileadmin/downlo...nect/IA-IPfonie_extended_connect-1.3-1504.pdf
page 17 is the number format

 

[Hans Kuhl]

Thanks for reply, but where can I format all outgoing numbers to this "<sip:+49..." format ?
PS: obviously most of outbound calls, about 99% do work!.....

 

[StefanW]

could you determine where the 040XXX number originated from?
An extension?
Incoming from another trunk forward to external?

 

[Hans Kuhl]

from an extension, we use phone model "Yealink T21P E2" with latest firmware
other destinations in this city work, the called number is reachable by mobile phone.

Log after adding outbound rule to format number:

[Hans Kuhl]

it's still not working, no more ideas ?

 

[YiannisH_3CX]

If the issue is only with the specific number and you have tried the correct format then i would suggest the next step is to contact your provider and ask them why the calls to this specific number are rejected. If the not acceptable here message originates from their IP then they should be able to provide some insight as to what the issue is
