RFC Support
PRACK (RFC
3262)
RFC 3262 defines a mechanism to provide reliable transmission of SIP
provisional response messages, which convey information on the processing
progress of the request. This uses the option tag 100rel and the Provisional
Response ACKnowledgement (PRACK) method.
Select Supported or Required to have the Device include a SIP Require/
Supported header field with the option tag 100rel in all INVITE requests. When
the Device receives a SIP response message indicating that the phone it called is
ringing, the Device sends a PRACK message to have both sides confirm the
message is received.
If you select Supported, the peer device supports the option tag 100rel to send
provisional responses reliably.
If you select Required, the peer device requires the option tag 100rel to send
provisional responses reliably.
Select Disabled to turn off this function.
Session Timer
(RFC 4028)
Select this to have the Device support RFC 4028.
This makes sure that SIP sessions do not hang and the SIP line can always be
available for use.

Replace dial digit '#' to '%23' in SIP messages.
Remove ':5060' and 'transport=udp' from request-uri in SIP messages.
