I have 3+ sip trunks, I have configured the outbound routes with dial patters to allow 9 for one line, 8 for the second etc.
I would like to have line keys (Sangoma S705) showing if the trunk is busy/flash for incoming call on that trunk and also the ability to press the blf key to allow me to dial out on that trunk.
is this possible? any clues how if it is possible?
