Arun,
Your query doesn't have enough context to understand the case. It does
however appear to more likely to be something that should be answered by
someone in the 3GPP IMS community. If you want an answer here please
spell out your case in much more detail.
Thanks,
Paul

Hi Team,
Need some info, can UE be allowed (as per rule) to send SIP REGISTER
requests to all the received P-CSCF addresses from NW (during attach) ?
For Ex.
If UE received 5 P-CSCF address during attach
Is it allowed to send REG to address at the same time
UE REG to P-CSCF-1--->
UE REG to P-CSCF-2--->
UE REG to P-CSCF-3--->
UE REG to P-CSCF-4--->
UE REG to P-CSCF-5--->
<--- 401 from P-CSCF-2
<--- 401 from P-CSCF-3
<--- 401 from P-CSCF-5
UE AUTH-REG to P-CSCF-2--->
UE AUTH-REG to P-CSCF-3--->
UE AUTH-REG to P-CSCF-5--->
<-- 200 OK from P-CSCF-5
So, UE finally connected to P-CSCF-5
I know this may increase signalling load on NW, but want to understand is
this flow allowed as per rules ? Or there are any restrictions please help
on understanding
