I have a 8861 that when configured for VPN service mode it stays in that mode, I have detect network so I though when its in the office it would connect as Enterprise mode and then offsite would do VPN? Is there a bug in sip88xx.11-7-1-17 firmware?
I experienced this a while back and it was a bug. i will try and dig out tgr details for you
