I ve a few sangoma phones S505 and ive the follwing issue.
all incoming calls are going to a ring group with 3 phones. (reception)
and then the reception phones are tranfering the calls to the appropriate department.
The problem is that i cannot see the caller-id of the external caller but it sends the caller id of the recetption phone i.e the extension number
How can i overide these, because with previous Grandstream phones i didnt have any problem with the caller - id
