Aastra's VentureIP system was deployed over a network of Extreme Networks' Summit switches. Because the VentureIP phones now do not work across routed IP links, we set up the Summit switches with Layer 2 switching only enabled and Layer 3 IP-routing disabled.
Telephony features - forwarding, conferencing and the like - were tested with the three phone sets the vendor provided in the lab and with remote phones via a PSTN analog FXO trunk connected to the VentureIP Gateway. The remote phones were TDM sets on a Lucent/Avaya Partner PBX.
We manually assessed call quality. Latency was measured by injecting a tone into one phone's handset, and clocking the one-way delay until arrival of the tone at another phone's handset connection.
