Hi Folks,
Just a small bit about the registration behaviour of Registrar server to
take care of errorneous condition;
1. UA sends REGISTER message with Call-Id 1 and from IP Address 1 to
Registrar server. Registrar server stores the location (IP1) of UA.
2. UA application crashes (power down, bug etc) and restarts, so DHCP server
assigns IP2 to UA. UA again sends REGISTER message with Call-Id 2 and from
IP2. Registrar server stores new location (IP2 along with IP1) of UA.
Now Registrar server has two registration bindings of same physical UA viz
IP1 and IP2. Till the timeout of IP1 (by default 3600 seconds), that binding
(IP1) shall remain live in the registrar server. Any proxy module requesting
registrar sever for the location information of UA gets two binding viz IP1
and IP2 however IP1 nowhere exists in the network. Any solution to take care
of this?
Best Regards,
Vivek Batra
