Nortel preferred configurations

Preferences > Advanced > No login server available.
• Configure only the G711 and G729 voice codecs for the IP Softphone
3456.
• On client, Nortel recommends a fixed port range defined under Account
Settings > Topology > Port Range to set the port.
• Ensure the registration refresh time is set to five minutes. This keeps the
registration timer short enough to recover quickly in case of network
failure.

selected.
