[Freeswitch-users] Mitel 52xx Broadsoft SLA/SCA Issues

[aromberg at gmail.com]

Here's the quick synopsis:  Freeswitch on CentOS 6 freshly installed 2
days ago. Freeswitch was grabbed via git.  Phones are Mitel 5220 SIP
phones that are in SIP mode.  Mitel has a Broadsoft implementation
called SIP_SCA in the device registration.  There is 1 Cisco 7960 but
its not configured at all for the shared extension.

I can't get it to work.  I *think* I have it narrowed down to the
presence ID being different on a per-phone basis.  The LEDS show the
correct call status (on-hook, ringing, on hold, etc).  However, when
you press the shared line from another phone, it dials the extension
again and goes straight to voicemail/busy instead of seizing the line.
All extensions are configured correctly (calling the shared extension
from the Cisco results in both phones ringing and able to pick up the
call initially)

Logfiles are located at:

Each one has the same actions:

Mitel phone 1 (192.168.1.106/extention 1002) calls Cisco Phone 2
(192.168.1.103/#1000) on Shared Line 1003.  Cisco answers.  Mitel
Phone 1 puts call on hold.  Mitel phone 2 (192.168.1.100/#1001) tries
to pick up Shared Line 1003 and then hangs up when it hears the
voicemail system.  It normally does this twice.  Then Mitel phone 1
picks up Shared Line 1003 and ends it.

No matter what order the steps are done with whatever phone (well,
except the Cisco doesn't have a shared line), the results are the
same.  Picking up the shared line results in a forward to the VM
system

Thanks,
