Avaya 9640 phone losing VPN settings

Avaya 9640 phone losing VPN settings

Avaya 9640 phone losing VPN settings

(OP)
My company has about 350 homeworkers using Avaya 9640 phones configured for VPN.
We have a problem where 3 or 4 phones a week will lose its VPN settings and display waiting for LLDP.
When I check the phone it has defaulted back to group 0.
To reconfigure the VPN settings, we put the phone on the LAN in the office, change to Group 4 and the phone will download the VPN settings from the 46XX file.


The phones are using 3.20s firmware and connect to a Cisco ASA.
Any suggestions would be greatly appreciated.

FWIW, try the last 3.2.8 firmware.

I haven't tried 3.2.8 but when I upgraded phone to 3.26A I found it was not compatible with certain broadband routers, some routers were OK
The phone displayed the error VPN tunnel failure, “needs DNS server IP address”
I then tried 3.25A then 3.23A then 3.22A still had the VPN tunnel failure.
Now that 3.2.8 is available I'll try that, thanks

Still keen to hear if anyone else has fixed the 9640 VPN phone losing the configuration problems?
