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

[Wes Sisk]

3rd gen phones (see: https://supportforums.cisco.com/docs/DOC-8131#Definitions)

*should* get http download in 9.3(1) so long as things go as planned with:
CSCsy15970

this is future planning and therefore subject to change.

Regards,
Wes

10-20 minutes sounds like the time to download the larger loads required by the 79x2 and 79x5 loads. When you reset the phones they re-attempt TFTP. The phones will spin on TFTP transfer for 10-20 minutes, then give up most likely on a failure, and register using the old phone load.

If you check one of the phones that experiences this issue - either in RTMT or in the phone webpage, has it successfully upgraded to the 9.x release or is it still running the 8.x release such that they would attempt upgrade on next reset.

I was not under the impression that 79x2 and 79x5 model phones had http transfer of phone loads yet.  That would be a good point of clarification as to how the phones are attempting upgrade and if any problems occur in that attempt. Usually detailed TFTP traces are adequate.

Hey guys,
 
We are gradually upgrading our fleet of 7965G's to SCCP v9 software from v8.
 
We have found an issue at remote sites (higher latency) where phones (with any 9.x firmware) are taking upward of 10-20 minutes to register! This delay seems to only occur when a full power off / power on occurs.
 
Downgrade the phones back to v8.x and whola! No problem.
 
We are going to try and simulate this in the lab with a WAN sim and then probably get TAC involved. I suspect it has something to do with the extra latency involved but as mentioned we have had no trouble with v8.x software.
 
Has anyone come across this problem? It seems a bit oddball I know.
 
Any hints or suggestions are most welcome.
 
Thanks,
 
Aaron.
