Mesh Applications

CPARC maintains multiple applications and services available over the mesh. Some mesh applications are only accessible from the AREDN mesh, while others are accessible from the internet as well.


There are is a VOIP PBX on the network hosted at the Clark Valley Site. If you’d like an extension off the PBX, contact calpolyradioclub (at) gmail (dot) com.   A Grandstream phone is preferred for best compatibility, but others will work (as long as they are capable of SIP calls).  The models that work well are:

GXP 1610: one line, no POE

GXP 1615: one line,  POE

GXP 1620: two lines, no POE

GXP 1625: two lines, POE

You can also use a softphone (software phone).   Linphone for MacOS, Linux and Windows works well.  It can be downloaded here.

VOIP voice chat

We run a Teamtalk server on the network.  It supports text, audio and video chatting, and also allows you to share files and your desktop.  It can be used at any time and we encourage you to hang out there, just as you would on your local FM repeater.  

The Teamtalk client software can be downloaded here.   If you’d like to participate, contact the club for a personal account on the server.   The server hostname is w6bhz-aprs-pi.local.mesh  (it’s all needed; enter it as shown).

On the main screen when first installed, the third icon from the left on the top is “Enable Voice Activation”, and it’s defaulted to Enabled.  Click on it to disable VOX.

Under Client / Preferences set:

Your Nickname.  We use <name> <callsign> <QTH>.

Your Push To Talk key.   Left Alt works well.

Under Client / Connection

Check the first two boxes:  “Connect to latest host on startup” and “Reconnect on connection dropped”.

Under Client / Sound System – make sure it’s configured for your preferred voice input/output devices.  A USB headset with microphone boom provides excellent audio.
