Phone Ports Collaborative Features
While Phone 1 and Phone 1 can function independently of each other, the device also offers some
collaborative features to enable the ports work together as a mini phone system.
With the factory default digit map and call routing rules, you can dial a single “#” digit (the pound or
hash key) to call from one Phone port to ring the other Phone port. Depending on the current state of
the called phone, one of the following can happen:
● Case 1: If the called phone is idle (on-hook), it rings normally with a special Caller-ID that
indicates the call is from the other Phone port.
● Case 2: If the called phone is already on a call, the calling phone barges in to join the call.
● Case 3: If the called phone is on-hook with a call on-hold, the calling phone picks up and resumes
that call.
● Case 4: If the called phone is ringing, the calling phone picks up and answers that call.
● Case 5: For all other scenarios, the calling phone hears a busy tone.
You can prevent the calling Phone port from doing 2, 3, and 4, by setting the
EnablePhonePortBargeIn parameter to False for that port. In that case, 2 becomes normal
call-waiting on the called phone, but the calling phone hears a busy tone for 3 and 4.
You can also transfer an external call from Phone 1 to Phone 2 in the usual way: while connected on
an external call, hook flash and dial # to ring the other phone, then hang up to transfer when the caller
phone rings or answers.
For incoming calls on any trunk (SP1 through SP4 or PDMS-SP Service), you can set the
corresponding inbound call route to ring only Phone 1 or Phone 2 or both. The default inbound
call routes are to ring both Phone ports.
For outgoing calls, each Phone port has its own digit map and outbound call route configuration.
These ensure that you have full flexibility in allocating trunks for making calls from each port
independently. Each port can have a different primary line assigned. However, the default is to set the
primary line to SP1 for both Phone ports.

The device supports service features via the handset connected to the Phone port.
You can use the following Star Codes to access the indicated features. Poly Star Code-enabled
