[SR-Users] MSILO: SIP stored offline MESSAGE repetitive delivery

[M S]

Hi,

When kamailio dumps the messages to destination party upon register, do you
see its reply received by kamailio correctly? Most probable cause of the
problem is that kamailio does not receives 200 OK for dumped message from
destination party and assumes message delivery failure, therefore it stores
the message again. This is all done automatically be msilo module.

Thank you.
