More advanced functions are provided here, these are optional settings. Please
check what you need for the IAD settings.

conveyed with the packets transmitted
to other places.
The SIP request and response
messages sent by the IAD will be
encoded with the device name of the
user agent.
Encode SIP URI with user=phone

A SIP URI can identify a
communication resource. It contains
