Have you added the extra channel for each extension related to the Sangoma phone in the panel manager?
It's under Buttons, and you'll need to click on toggle advanced fields. For each extension there's a field called 'Extra Channel'. For the Sangoma phone you'll need to add the related extension which I think is something like PJSIP/98### where ### is the related extension.

I know I had to add an extra channel under Buttons > Toggle Advanced Fields.
The extra channels I have added are PJSIP/98### where ### is the extension.

I have the softphone plugin set up and successfully taking inbound calls, but on some outbound calls the softphone doesn't send or receive audio from the PBX. When I check the call recording it only has audio from the external recipient.
