9608VPN Freezes after 30 Second Call

[desphoneguy]

Another customer another issue.

I have a 9608vpn phone connecting through cisco VPN client to a remote site. The VPN establishes the phone registers. I can go off hook and get dial tone as many times as I want. If there is a call established that lasts longer than 30 Seconds the either person hangs up or in the middle of the call the phone freezes up.Then eventually goes into restart.

It is a Cisco 520 Router, IP Office 9.0.5 rel 972, 9608 with 6.3116.

Any ideas?

6.3116 is quite old. Maybe try a more current release.

May seem like a dumb question but how do you upgrade the 9608 phone. I thought that the version was based on the IPoffice system version that is currently installed on the IPO

UPDATE

I managed to download the most current version of H323 for 9608 Ip Phones

Took awhile to find documents on downloading it a phone, however, the only way I could get it on the SD Card was to remove the SD Card and then insert in my PC. Then copied and pasted the new files.

Then rebooted phone a couple times and the new software was loaded.

And it indeed fix my problem

Good to know. What version do you use now?

Why didn't you upgrade your IPO to the latest R9.0?
It's sp 12, 7 versions newer.
