[SIPForum-discussion] Registration timer

[Boris vercher]

You have to re register at «  registration timer  / 2 » even if a sip
registrar have to support  “ registration timer  “ + 10s, before clearing
resgistration, if no register keep alive occur.

 

So re registration occurs before “ registration timers expires “. Otherwise
you can be unregistered during 1 or 2s ( for example )

 

When you reregister the timer is reset to the new value.

 

However when an UA send a register with “ registration timer  “, the value
that will be used, will be the timer “ registration expires “ sent back by
registrar. And not the original one sent by UA.

During the SIP registration, an re-registration will occur only when the
registration timer expires. My question is, "Will the 'expired timer' from
the cache is cleared for every cycle before the re-registration occurs?"

 

 

 

Thanks in Advance
