Hi,

Ok let's look at some things that can affect this:

- Are they all on the same LAN and subnet as the PBX or are you maybe using STUN mode for some of the affected phones?

- Have you tested extension-to-extension calls too, or is just external calls that drop perhaps?

- Have you made calls using the webclient to see if they also drop at 15 mins?

- Was the system modified in any way? (ie. Parameters changed)



PS: There is no GXP1790, I guess this was a typo?

Only external calls

- Have you made calls using the webclient to see if they also drop at 15 mins?
No webclient only ip phones

- Was the system modified in any way? (ie. Parameters changed)
No its on the default 3CX settings

Ok,

Then run some tests with internal calls, and also an external with the webclient to find out.

Also you have not confirmed if any of the deskphones are possibly using STUN.



Important Note: if you find out that only external calls drop at 15 mins. then you are facing an issue with your provider, and in that case we can advise accordingly.

If it is external calls only, you might check the 3CX Activity Log to see which end actualy ended the call, was it your provider?

Do your trunk setting with "support reinvite"checked? if so try to uncheck and do a call test
