[OpenSER-Devel] [presence] delay notify?

[Anca Vamanu]

Hello,

A solution to this problem would be to not to send a reply to a Notify 
for which you don't find a matching dialog, just to drop the message. 
This will force retransmission and eventually, the processing for the 
Subscribe reply will be finished and the record will be found.

regards,
