Can't dial out from second handset


We have a FreePBX system.

I recently set up a DP720 handset with a DP750 base station and it’s working well.
I’ve just added a second DP720 to the base station and it won’t dial out.
I can place calls to handset 2 and answer them, but nothing happens when I dial out from HS2.

Any ideas?


Usually something on PBX is wrong. Catch packets on DP and see if you can see outgoing invite.


Check the extensions permission level for 642.


I’m not sure what you mean.
As far as I can tell both extensions have the same settings.
642 existed before, but it was a BT cordless via a old Grandstream ATA.


Can you show the extension settings for 642?
