Hi,

I would suggest you to check the MRGL applied on the phone configuration page.

Check if any of the MRG in that particular MRGL has a conference bridge listed under it.

One other troubleshooting step which you can try is switching the device pool and the MRGL of a working phone to this phone and see if it works.

Please rate and mark correct if helpful

mrgl of all phones is same still issue persists. And if it was a mrgl issue then internal conference would work? (In my case it is working)

its little strange that i can take two external numbers into the conference but not one external and one internal 

my ext. + internal ext 1 + internal ext 2 = working

my ext + mobile 1 + mobile 2 = working

my ext + internal ext 1 + mobile phone = not working

Hi Ramiz,

Would it be possible for you to attach a set of traces for the last 2 scenario.

1) my ext + mobile 1 + mobile 2 = working

2) my ext + internal ext 1 + mobile phone = not working 

I can have a quick look at it.

Please do give me the following details.

calling number, called number conferenced number and the timestamp for the two calls.

Which traces you require? Debugs from the local gw?
