9608 remote phone no VPN

9608 remote phone no VPN

9608 remote phone no VPN

(OP)
Hi all,

Try to make this as short as possible.
Phone system is a 8.1, have numerous IP phones in different locations 9608s & 1616s all using VPN.
Trying to add another IP Phone 9608 via Remote Extension, in a house just to save having to have more equipment & cost by not using another VPN router.
Just to give the details, location A has the phone system, digital & 1616 IP phones.
Location B, just across town from location A has 5 1616 phones off a VPN.
Location C, located out of my state, has 2 9608 phones using VPN.
Locations D & E each have 1 1616 phone using VPN. Located in two different states.

Got the IT guy to open required ports for the remote phone, tested it first in my office, all came up & working good.

Noticed then only location B's phones were down. Luckily, at least, in the same town.
Went onsite all saying "Discover xxx.xxx.xxx.xxx" checked programming in the phones, still not working.
Deleted my new STUN settings I used for the remote phone, had to reboot system to save.
Phones (at location B still) came up saying "invalid password press #"
Kept trying password, went in Manager to change passwords, even deleted an Extension/User & recreated it.
Still invalid password.
Then I disabled (unchecked) my H323 Remote Extension Enable, again had to reboot to save.
Phones said invalid password, pressed #, entered password & phone(s) came up & working.

Obviously now my remote phone still in my office is down now, everybody else is good.
I have plenty of IP endpoints available.

My questions are, can you have a remote phone with others on a VPN, & why did just location B go down, but all others stayed working.

Sorry so long, just wanted to give all the details.

Thanks to all replies.

Thanks derfloh,

That's the route I was thinking about trying.
Never set one up before, using the VPN client, so doing as much research on that now & waiting for the IT person to call back with the settings he wants me to use.

Any ideas with my original questions???
Just so weird it only affected that Location B's phones.

RE: 9608 remote phone no VPN

It is hard to say what caused it. Did you change IP routes? That could do it...

Other then that maybe some kind of subnet mismatch/match. I know remote workers don't work if the remote user is on the same subnet as either interface on the IPO. Maybe your user's subnet matched the remote site, then the system saw that one phone as behind NAT, and assumed all phones on that subnet are behind NAT which means they need remote worker enabled to work. Shot in the dark guess to be honest.

The truth is just an excuse for lack of imagination.
