[SIPForum-discussion] Regarding subscribe request

[Nitin Kapoor]

Vikram,

It is possible to send the subscription twice, Basically the subscription
can be refreshed by sending another SUBSCRIBE within the dialog before the
expiration time. A server accepting a subscription returns a 200 OK response
also containing an Expires headerfield.The expiration timer can be the same
as the request, or the server may shorten the interval, but it may not
lengthen the interval.

Thanks,
Nitin Kapoor
