5610 VPN Phone cuts out

[wingnutkev]

The VPN phone connects great and I can make and receive calls fine now.
The issue is there seems to be some kind of registration timer or setting where the phone either loses or renegotiates the tunnel at around 20 min. I can not get a call to last longer than about 17 min or a combination of calls. The call drops audio and disconnects the caller. I can then hang up the VPN phone, the display states VPN tunnel lost and proceeds to reestablish the tunnel and you can recover, but the call is gone. I'm wondering if there is a setting in the VPNsettings.txt file to fix this but have not been able to find an answer.
We are using Check point Safe@Office firewalls and IPO 5.0(15).
I don't think it's in the firewall. I can use a Checkpoint VPN client and a Softphone and have not encountered the same issue, the call goes well beyond 20 min.

Any help or direction is appreciated.

Set the timer higher.

What timer?

I think it is the lifetime timer.. somewhere in the VPN settings on the phone. I think you can go up to 5 days. set it seconds.

Indeed the lifetime timer
Set it for 24 hours and reboot the phone in the middle of the night.
Then you will not have any problems anymore

Is the lifetime timer a setting in the vpnsettings.txt or the phone. I've gone through the phone and didn't see it. If it's on the vpnsettings.txt I haven't found the parameter to set yet.

Again thanks for any help.

It should be a setting on the phone and or in you VPN router.
