If I use the split key, on the 5340 set, then I can speak to each party individually. I have tried this on both an analog set and a 5340 set. Both act the same.

Remember also that VoIP phones connect the call by TCP packets, but talk (voice traffic) over UDP. \| VBC Salinas \| Valley Baptist Church, Salinas - worship and prayer for Salinas California

The phone I am testing with says "3 party conference" in the display but there is no audio for anyone. If I hang up then the two other parties are connected and they can talk.

This could be a DSP kind of problem also right? This system has been installed for 5-6 years and the conferencing worked up until a few months ago. The customer isn't sure exactly when it stopped working because the conference feature is used rarely but it does get used.
