Problem
The initial outgoing INVITE for an early offer SIP trunk call does not contain an SDP.
Solution
1. Verify that you checked the Enable Early Offer for voice and video calls check box on the SIP associated with the early offer trunk.
2. Verify that the SIP trunk is not in IPv6 only mode or dual-mode trunk with ANAT or media preference set to IPv6.
3. Verify that calling device is not an IPv6-only device.
4. If initiating calls from pre SCCP v20 device or H323 Slowstart device or if this is a delayed offer incoming call, verify that MTP allocation is taking place.
5. Ensure that the caller or SIP trunk media resource group list has an MTP available. Verify that the MTP firmware supports getPort capability. If the MTP image does not support getPort capability, upgrade to a newer image, IOS release 15.1(2)T or later.
6. For an SCCP v20 calling device, verify that the device provides the media port in StationPortRes/ DeviceMediaInfoRes. If not, check for a timeout event—GetPortResponseTimer or TimeoutWaitingForPortInfo.
