Greetings,
Proxy compiled with TLS support, tls is not turned on
Routing script inclulded below. Underlying database is Sybase.
The following is happening:
There are 25 users having as a contact each other. Softphone is Bria.
Without any calls, just subscribe/notify
proxy is running out of the socket in one hour. The users are or outside
coming via corp firewall, or if inside, the route is setup the way the going
via corp firewall, so they are natted. Proxy is in DMS on the same network
as firewall. There are no problems with nat traversal.
Daniel, could you please take look at the script?
Thanks a lot,
Toly.
this is from log:
