Solved Adhoc Conference calls not working

[Reso]

Server OS : Windows 10

3CX Version: 16.0.676
Phones: Grandstream 2135 and 1628 with the supported firmware.

I have an odd problem. I am trying to create ad hoc conference call (https://www.3cx.com/blog/voip-howto/create-conference-using-desk-phone/) using the above mentioned models. I can call 700 from all phones and get the voice prompt. However it doesn’t create or let me join a conference call. After a few seconds it says “Invalid Pin Number”. I don’t have a Pin set for the organizer to enter.

Here is the odd part. I can make and join conference calls on model 2135 WITHOUT phone provisioning. If I provision it says “Invalid Pin number” again. The models 1628 gets the voice prompt “Invalid Pin number” either provisioned or not. Please help.

Hello,

You probably have a PIN requirement. Read the article again on step 2. You will find your PIN in the management console under Settings > Conferencing > Audio

Note: We are discussing in the context of properly provisioned phones without custom templates to get the expected behavior.

Thats the problem. I removed the PIN requirement but its still giving me the same voice prompt. The only phone i can make the conference call is 2135. That also without provisioning. Once i provision that phone, i get the voice prompt "invalid pin number".

I enabled verbose logging and made a call to 700 and dialed a conference ID. I got the same "invalid pin number". Above is the resultant log. Please let me know if i am missing anything

 

[Reso]

ok. I tried to do more tests, however i couldnt this time. Provisioned or not.

Earlier I had added a extra IP address of a different subnet to the 3cx server because i was doing another test on phones of that subnet. (the phones i used to test conference were on the same subnet as the 3cx server). I removed that IP and restarted the phones (provisioned) and the server and now everything is working fine . Thank you all who commented.

I'm glad to hear it was resolved
