[sipx-users] OPTIONS


Hi,

 

We have a SipX installation and we have connected it to a sip trunk. Everything works very well but SipX responds with an error response to the OPTIONS messages sent by the trunk operator. The following messages were captured in promiscuous mode, so even messages inside the SipX server would be visible but there are none. It seems that SipXproxy responds 406 by itself. Why?
