[Freeswitch-users] freeswitch interop issue

[mark morreny]

Hi,

I am having trouble receiving calls from a sippy voip server.
Freeswitch returns 400 for a normal INVITE I received from my vendor.
Does anyone know what is wrong?  Is there anyway to configure
freeswitch to get this interoperability issue resolved?
