[OpenSER-Users] Openser sending 513 Message Too Big

[Aadilkhan Maniyar]

Hi,
 
Please find my openser.cfg file below. Whenever I try to call a
softphone registered with Openser from another softphone (also
registered with Openser) i get a 513 Message Too Big.
I guess there is a loop in the configuration file but I am unable to
find it out. 
 
Any help would be appreciated.
 
Regards,
Aadil
