[SIPForum-discussion] which timer UAC start on 491 response ?

[Ivan, Martin]

Taken From 3261

"If a UAC receives a 491 response to a re-INVITE, it SHOULD start a
   timer with a value T chosen as follows:
 
      1. If the UAC is the owner of the Call-ID of the dialog ID
         (meaning it generated the value), T has a randomly chosen value
         between 2.1 and 4 seconds in units of 10 ms.
 
      2. If the UAC is not the owner of the Call-ID of the dialog ID, T
         has a randomly chosen value of between 0 and 2 seconds in units
         of 10 ms."

 

 

Is randomly chosen value taken from interval of sip T2 timer which is 4s ?
