[reSIProcate-users] how can i use 18x provisional response with reliability

[Tanim <tanim@xxxxxxxxxxxxxxxx>]

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.
