[SIPForum-discussion] Multiple Expire parameter in Contact header

[Kutay OZDOGRU]

Hi all,

 

I have a sipserver that registers multiple clients to IMS side however,
when my sipserver gets 200 OK message for De-register as below, it faces
confusion because of 2 expire parameters.

 

m:

<sip:2124400004 at 137.116.157.205:5061>;description="Login";expires=84703;

+sip.instance="<urn:uuid:c19497bf-9ba3-404a-b77f-0d6014021eed>";reg-id=1

,<sip:2124400004 at 47.133.146.132:5060>;expires=0

 

 

There is no expire header in 200 OK message so expire parameter is in
contact header but why remote sip server sends me

2 different expires....

 

How can I be sure about which expire should I use? :S

 

I have a confusion on this point. I cannot find any information about
this in RFC3261... is it applicable?

Do I have to  handle this?

 

Could you please give me your comments?

 

Thanks,

Kutay
