•
The IP PBX does not require UCA server involvement to route a call to a CA50.
NOTE The specifics of the IP PBX are entered into the UCA server so they can be downloaded and
programmed into a CA50 at login, enabling the CA50 to contact and register with the IP PBX. After
registration is complete, a PBX based call can be routed to a CA50.
•
The UCA server is required to place a call from a CA50. In order to place a call, the CA50 must access and
use a dynamically accessed phone book located on the UCA server.
NOTE When the phone book is previously viewed from a CA50, any portion of the phone book viewed from the
CA50, and only this portion of the phone book, is cached on the CA50. If the UCA server is temporarily
not accessible, the CA50 can access the cached phone book information.
IP PBX Integration with the UCA Server
The site IT administrator configures the UCA server with PBX information (IP address, available extensions, etc.)
enabling CA50 voice calls to be routed to and from the IP PBX.
The following settings must be entered into the UCA server to work with the IP PBX:
•
Phone.Gateway.IPAddress
•
Phone.Gateway.Port (note the phone Gateway port for H.323 is 1719 (port 5060 for SIP and port 2000 for
SCCP)
•
Phone.Gateway. Protocol Type
•
Phone.Peer2Peer.Enable (port 1720 for H.323 and port 5060 for SIP)
•
Phone.Peer2Peer.Port (note the peer-to-peer; direct CA50-to-CA50 IP based call; port 1720 for H.323 and port
5060 for SIP)
•
Phone.Gateway.CallPark.Enable
•
Phone.Gateway.FAC.CallPark
•
Phone.Gateway.FAC.CallPick
For details and definitions of each of these parameters, see
phone settings into the UCA server Web Console, see
Additionally, to enable a CA50 to access phone extensions contained within the IP PBX, they must be mapped into
the UCA server. See
Losing a Connection Between the CA50 and IP PBX
When the connection between a CA50 and IP PBX is lost a No Phone error message displays on the CA50. Users
in No Phone state do not appear in the Phonebook of other logged in users.
The connection loss can occur under the following circumstances:
•
Temporary network related issues. In this case the connection loss is transient.
•
Prolonged network issues.
•
IP PBX is down.
