I am working with FS 1.6.19.

I am facing a situation when FS is not sending Notify packets to SIP endpoints which have subscribed for callee presence.

To explain scenario,

I have 3 SIP endpoints : 

EP 1 :1000

EP2 : 1001

EP3 : 1002

EP3 has subscribed for 1000 and 1002 presence information.

When i call from EP1 to EP2,FS sends Notify packet for EP1 to EP3 but not for EP2.

Should FS send Notify for EP2 as well ? or this is the functionality of FS itself ?
