Vocera SIP Telephony Gateway Ports

When you open the vgwproperties.txt file, you can set the following properties to configure Vocera SIP Telephony Gateway ports:

Table 1. Vocera SIP Telephony Gateway port properties

Property

Description

VTGCallSignalingPort

Sets which port that Vocera SIP Telephony Gateway listens on for SIP signaling. The default is 5060.

VTGBaseAudioPortNo

Sets the base UDP port for receiving audio packets from Vocera badges and smartphones. The default is 5300.

By default, Vocera SIP Telephony Gateway opens up to 256 UDP ports to receive audio from Vocera badges and smartphones.

Important: If you change this property to something other than 5300, you must also add the following property to the \vocera\server\properties.txt file on the Vocera Server, and then stop and start the server to load the property:

IPBasePhonePortNo = PortNumber

where PortNumber is equal to the port specified for VTGBaseAudioPortNo.

VTGRTPBasePort

Sets the base UDP port for receiving audio packets from the IP PBX or VoIP gateway. The default is 8700.

Each client session uses an RTP and an RTCP port. Therefore, the total number of UDP ports for Vocera Server or Vocera Client Gateway to Vocera SIP Telephony Gateway audio is two times the number of VTGMaxChannelsSupported, which is set to 256 by default, resulting in 512 ports allocated by default.
