Hi Adrian,

CISCO do claim to support third party SIP clients, and I have registered
softphones against it in the past.

I don¹t know why in this case there is no SDP, and I will look into this
further.

There is no SDP with any type of supported media in this Invite.

You are using Blink against a non-standard compliant corporate PBX solution
that works only with approved phone devices by Cisco.

What do you want to see happening except rejecting it?
