[Sip] Resubmitted INVITE request for 421 and 420

["Vavilapalli Srikanth-A19563" <srikanthv at motorola.com>]

Hi

 

I have a doubt related to resubmitting of the INVITE request for 421/420. Can any one please clarify me?  

 

While re-submitting a INVITE request upon receiving a 421 Extension Required/420 Bad Extension, Are there any recommendation of using the same Call-Id/From tag of original INVITE request in the resubmitted request? If so, is there any reason/use-case for such recommendation?

 

Regards

Srikanth
