Thanks alot for your quick replies,
I didn't have double <> for To and From in my question if you check the
first thread again. :)
Want to add one more thing, Just to cross check, when I sent a NOTIFY packet
from Asterisk to extension directly, it works showing me blinking red light
on the phone!. And I can configure MWI on Grandstream phone.
Please have some more thoughts,
Thanks,

Good eye! That too.
Basically, Granstream sucks. Don't bother.

Now to implement MWI i send NOTIFY packet from
Asterisk to Kamailio and
from kamailio to SIP extension (Grandstream GXP2000).
here is the packet that travels from kamailio to extension and the
response
sent from extension to kamilio.

NOTIFY's are in-dialog requests. Your From and To header are missing the
required tags (and look a bit suspicious by themselves too because of the
double<>). The grandstream probably can't match the NOTIFY to the correct
subscription and follows a code path that for some reason decides to
answer
415 instead of a 481.
