Matrix PRASAR UCS System Manual 677
• Call Park-Personal Orbit: Each IP Phone connected as an extension has one Personal Orbit. Calls
parked in personal orbit can be picked up only from where the call is parked. So, no other person can pick
up this call. Multiple calls can be parked in the Personal Orbit at a time.
Extension users can park the call either in the General Orbit or the Personal Orbit by dialing an Orbit Number from
1 to 9, where:
• 1 is the Personal Orbit Number.
• 2 to 9 are General Orbit Numbers.
After parking a call, the extension user can continue to make and answer other calls and use other system features.
For Standard SIP phones, PRASAR UCS supports Call Park and Retrieve using REFER Message. For a
list of IP phones on which this feature has been tested, see “PRASAR UCS Features tested on IP Phones
of different Brands” in the Appendix.
General Call Park - Auto feature is not supported on Standard SIP Phones.
How it works
A and B are extension users. C, D and E are callers.
Parking Calls in General Orbit
• C calls B.
• A picks up the call.
• As B is not present at his extension, A parks the call in General Orbit Number 2 by dialing the Access
Code.
• C is played on-hold music.
• A tries to find B (by either calling several numbers or by going in person or sending someone).
• The parked call remains in orbit for the duration of the Call Park Timer, which is set to 2 minutes by default.
• A finds B.
• B retrieves the call from another extension by dialing the feature access code for retrieving Call Park and
Orbit number 2.
• If A cannot locate B or if B cannot attend the call, A can also retrieve the call from his extension.
However,
• If neither A nor B retrieves the parked call within the Call Park Timer, the system will hunt for the extension
that parked the call (A) on the expiry of the Call Park Timer.
• Meanwhile, if A is busy, the system again keeps the call parked in orbit number 2 for the period of the Call
Park Timer. This process continues for the duration of the Call Park Release Timer, which is set to 3
minutes by default.
• If A is free, the system will ring on A's phone. A gets connected to C again.
• If A does not retrieve the parked call till the end of the Call Park Release Timer, C gets disconnected.
