[Asterisk-Users] 7960 utilize all lines

[Jan Baggen]

I have several 7960 phones with SIP image (7.3) and
Asterisk 1.0.1 on FreeBSD. 

When I have 2 active SIP calls on the 7960 phone there
are no available lines for additional calls. I tried
to configure 2 lines to the same SIP server but it's
still limited to 2 calls. How to utilize all lines?

-- Called user
-- SIP/user-acc6 is ringing
-- SIP/user-acc6 answered SIP/x.x.x.x-09a9a000
-- Attempting native bridge of SIP/x.x.x.x-09a9a000 and SIP/user-acc6

-- Called user
-- Got SIP response 486 "Busy here" back from x.x.x.x
-- SIP/user-0e44 is busy
