[OpenSIPS-Users] Strange errors forwarding requests

Thu May 6 11:16:35 CEST 2010

That might be :)

I'm now running into problems with the dialog module (which i use to limit concurrent calls).
Calls seem to stick in the dialog module (thus denying additional calls) while the endpoint isn't
listing the same amount of calls :/

Regards,
Erik
