You can set the following properties to configureVocera SIP Telephony Gateway ports:

Property

Description

VTGCallSignalingPort

Specifies the port to which Vocera SIP Telephony Gateway listens on for SIP signaling.

The default port number is 5060.

VTGBaseAudioPortNo

Sets the base UDP port for receiving audio packets from Vocera badges and smartphones.

The default port number is 5300.

By default, Vocera SIP Telephony Gateway opens up to 100 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 opt/vocera/bin/server/vstgproperties.txt file on the Voice Service, 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 port number is 9200.

Each client session uses an RTP and an RTCP port. Therefore, the total number of UDP ports for Voice Service to Vocera SIP Telephony Gateway audio is two times the number of VTGMaxChannelsSupported, which is set to 100 by default, resulting in 512 ports allocated by default.
