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

[Bogdan-Andrei Iancu]

Hi Abdul,

Not sure if this is applicable for us. According to the script sample, 
the fr_timer (in seconds) is 10....Is this value too low for a server to 
properly reply back ??

I guess that bug is Kamailio specific. We are on the safe side ;)
