Hi Tanim,
I was not the developer of this feature, and I haven't really kicked
the tires with it yet - so I'll let someone who has experience with
the PRACK implementation respond to these questions.

Thanks Scott. I have added 100rel as a supported option tag. But now the
problem I am facing is in callee side. How can I generate a provisional
message with offer/answer? The existing provisional function does not
provide this. What should the flow be like if I make a offer in the invite
and send a answer in the 18x response from the callee side? Also, what
should the caller do after receiving this 18x message, if PRACK is not
implement in DUM? How can this be implemented? It will be very helpful if
you point out some directions.
Thanks again. Best regards,

Looks like you need to add a 100rel as a supported option in the
MasterProfile. Take a look at
DialogUsageManager::validateRequiredOptions to see the code that is
getting triggered.
Also Note: Apparently UAS PRACK support is not currently implemented
in DUM. See the comments in MasterProfile.hxx (ln51) for more
information on the PRACK support in DUM.
Cheers,

Hello,
I am trying to develop a phone based on voip and I am using the
resiprocate
sip stack. I want to implement provisional response with reliability in
this. I set the UacReliableProvisionalMode to Required and
UasReliableProvisionalMode to Supported. But in the callee side, it is
generating a 420 message. What am i doing wrong? I found out that the
first
invite message could have any of the reliableProvisionalMode. What should
be
my course of action? I am using DUM. What the flow should be like if I
make
an offer in the INVITE request with a require field with 100rel.
Thanks in advance. Best regards.
