[cisco-voip] No SDP in INVITE to basic SIP endpoint.

[Adam Frankel]

You must check "MTP Required" on the endpoint and reset the device to 
have the SDP Info in the INVITE.  You'll also need to make sure the MRGL 
assigned to the device has a MTP which supports the necessary codecs for 
your Region configuration.

I'm evaluating a SIP paging server from Cyberdata.  I've configured it per
the docs,
(http://www.cyberdata.net/support/server/documentation/930280A_VoIP_Ceiling_Speaker_Cisco_Call_Manager_Server_Setup_Guide.pdf) 

and the paging server registers with CM.  However, when I call the DN, the
caller hears a ring, then error.

 From the captures and from the support folks at Cyberdata, there's no SDP
information in the INVITE.

SIP endpoints are new to me, so any clues on where to start looking?
