[SIPForum-discussion] RES: UAC′s register expires

[sreekant nair]

Hi All,

I would think that the Registration Refresh timer should expire triggering a REGISTER irrespective of the status of the UAC - whether in a session or not. 

The Registrar would remove the Binding if it does not get a REGISTER message to refresh an existing binding. The fall out would be that the Media proxy would not know "where" to route the incoming media resulting in the user perceiving that the other side is no longer responding(talking). This would most probably trigger the user to end the call or if there are RTP timers, that to expire resulting in terminating the session. 

My few cents. 

Regards
Sreekant Nair

Steven,
 
The UAS is aware of USC' register expires that the reason 
why the call is disconnected. The UAS knows that the UAC must send a 
REGISTER after few minutes (this time is defined in the expire information 
of 200 OK), but the UAC isn't sending this because the call is 
established.
 
Our doubt is: the UAC must send the REGISTER message while 
the call is established or the UAC can send the REGISTER only after the end 
of the call.
 
Attached to this email, there is a log of this 
situation.
