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

[Jason Aarons (AM)]

This seems normall But tftp time is tied directly to latency delay as every packet is acked, and 512k max packet size.

Peer firmware sharing and load server could help.

What exact version 8x to 9x?

Hopefully the switch to https or is around the corner. Tftp is great with small files but not large phone loads. The VIP12/30 had smaller loads.

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.
