ProCall Enterprisefrom V 6.2
PBX

Auerswald COMmander 6000R

Version 6.8 A/7.1A

Notes 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. 


Note 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.

Note on the use of call forwarding in the UCServer

If the Call Forwarding feature is used in the UCServer, the SIP lines must allow second calls in order to use the Call Forwarding on Busy feature.

Configuration of the telephone system Auerswald COMmander 6000R/FONtevo Commander

Participants for the use of ProCall must be set up with the standard VoIP telephone device type.

To set up the SIP line in the UCServer, the participant's phone number and password are required. 

Example screenshot: Participant – phone number and password

To view or change the password, click Edit PIN and Password at the bottom of the browser.

Note that ProCall 6.2 does not support encryption. Depending on the basic configuration of the telephone system, RTP encryption Only unencrypted must be selected for participants.

UCServer configuration

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

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 call protection 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..
