[reSIProcate-users] RSeq header in PRACK message

[Javier García Ocón <jgo@xxxxxxxxxxxx>]

Hi,

 

I?m testing a case of use with a PRACK message and reliable responses (100rel). This is the dialog:

 

The PRACK request must include the Rack header. It contains two numbers and a method tag. The first number is the value from the RSeq header in the provisional response (18x) that is being acknowledged. 

 

B2BUA (acting as UAC) receives the provisional response with the RSeq header. When the b2bUA (acting as UAS) creates the provisional response to send it to UA1 doesn't include a Rseq header.

 

Could you tell me if this functionality is enabled?

 

Thanks in advanced,

Javier
