[cisco-voip] 7965G delays registering on SCCP v9 firmware

[Ryan Ratliff]

89/9900s got it in 9.1(1).  I thought the older phones got it as well but haven't found confirmation just yet.

I have a wireshark of 7965 sccp load 9.2 doing port 69 from Friday with UCM 8.5.1SU3. 

What version load does http 6970?

All recent loads actually use http for tftp operations. It is over tcp port 6970 so isn't super obvious.  

To the problem I'd definitely look at a packet capture on both ends. Any devices doing wan acceleration or inspection?
