Hi Aadilkhan,

Try to debug the script by yourself by : 1) get a network trace to see how the request is processed (be sure and listen on all interfaces) 2) place xlog() messages through your script to follow the execution path.

Good luck, Bogdan

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
