This guide describes how to configure softphone features (SIP) for ProCall Enterprise in conjunction with a Panasonic KX-NS1000.

ProCall Enterprisefrom V 6.1
Telephone system
Panasonic KX-NS1000
Version 5.0

Information on the estos test environment

The softphone functions (SIP) of ProCall were tested in the estos test environment with the telephone system specified above. The tests were performed with a maximum of two lines per SIP end device. The following information was used during the setup of the telephone system for the login/registration of the individual SIP lines to the UCServer. 


Information on codecs and UDP connections

For the connection of SIP lines to the UCServer, the telephone system must support the G.711 a-law codec for the SIP protocol and should have this set as the preferred codec for all end devices.

Only UDP connections are supported.

Information on the use of call forwarding in the UCServer

Wird das Feature Rufumleitung im UCServer genutzt, müssen die SIP-Leitungen Zweitanruf zulassen, um die Funktion Rufumleitung bei besetzt nutzen zu können.

Configuration of the Panasonic KX-NS1000 telephone system

Set up as an extension

The SIP lines required for ProCall must be set up on the virtual board V-SIPEXT32.

PBX Configuration Menu – Slot – Virtual – V-SIPEXT32 – Main

Other must be selected as SIP Phone Type.

UCServer configuration

The connection to the PBX is entered under Settings in the UCServer Administration as SIP Softphone connection under Telephony – Lines.

  1. Add telephone system 
    Select the Panasonic KX-NS/NSX.
  2. Enter the connection to the telephone system under Softphone registrations as "SIP softphone".

  3. After setting up the connection, all SIP lines must be added under Softphone Registrations.
    For connection to a Panasonic KX-NS1000 must be specified:

    as username"Extension Number"
    (SIP Username)
    as password"Password" (The specification of a password is optional).

    On-site formatting

    Since the telephone system requires a special adjustment of the location's formatting settings, one can use the following settings as a guide. It should be noted that these may differ depending on the environment and serve only as a suggestion:

As of ProCall 6.2 Call forwarding in UCServer

With ProCall 6.2, the call forwarding function is available in the UCServer and activated by default. If this function is used with a connection to a Panasonic PBX, the target user will not see the caller's phone number, but the number of the forwarding user.
Panasonic recommends setting call forwarding via feature code.

To do this, disable the call forwarding option in the Line group properties – CTI features and enter the appropriate codes on the Feature codes tab.

For this purpose, observe the instructions and the notes in the manual Advanced functions for SIP lines via feature code

From ProCall 6.1 please note the following settings

On the SIP connection line group, it is possible to define what the UCServer signals to the PBX when:

  • the client is not logged in or do not disturb is enabled
  • the call is rejected by the client or no devices are available

The required settings depend on the telephone system and its configuration.

Example: The telephone system should redirect incoming calls to the mailbox if the ProCall Client is not logged in.

Problem: The PBX does not evaluate the busy here (486) sent by default from the UCServer and the calls are not redirected.

Possible solution: In the PBX, this setting is set up for Participant Unavailable, and Temporarily Unavailable (480) is selected for signaling on the UCServer.

Remarks

Callback timer for calls on hold

For users of ProCall Enterprise in connection with SIP softphone lines, it may seem unexpected that for a call on hold, a new call is signaled in the ProCall Enterprise Client call window after one minute has elapsed. The time duration of one minute described here is based on the default setting and may also deviate from this depending on the configuration in the telephone system.

The signaling of a new call for a held user via SIP represents a feature of Panasonic PBXs to remind of held users. This feature can be adapted to customer-specific requirements in the PBX configuration: PBX config. → 2nd System → 3rd Timer & Counter → Dial / Overflow / Callback / Tones → Callback allows the parameterization of the respective timers. In particular, the Callback Timer Hold(s) represents the time period until reminder for a held call as described above. Regarding the appropriate configuration options in detail, consider corresponding Panasonic information.
