Changed VPN and IP Phones won't discover IPO

[werdone]

I am currently running a 412 with version 4.0(7). I had a DSL circuit with kentrox router VPN'ed back to our T-1. the DSL service provider started overselling bandwidth out of the DSLAM. So I went to a T-1 back to our ISP. Now we have 2 T-1's back to our ISP who is using 2 MikroTik routers with a VPN (bridge mode)between them.

When I changed the settings in the phone. I can see the files getting to the phone from the distant end, but the phones sit in discovery mode. Is it because the ISP used a bridge mode and did not build an IPSec tunnel? Where is the disconnect?


P.S. I can get a ping to the IP office. These work fine on the DSL circuit (with the except of jitter, because of provider bandwidth limitations).


Thank you,

Drew

bridge mode should work equally as well as a vpn. you say you can ping the ipoffice from remote end and the ip phones power up and send/receive tftp files from the ip office manager. Then it seems everything is okay in the network set up and in the routes on IP office.

Is your remote pc network on same subnet/vlan as the remote phones?

If all is yes to above then problem is with ip phone programming. recheck the ip address settings.

All of the above is correct. The remote PC network, and remote phones are all on the same network, and subnet mask. IP phones are programmed as below

IP Address: 192.168.2.103-109
Call SVC: 192.168.1.150
Call SVCprt: 1719
Router:192.168.2.1
Mask: 255.255.255.0
File sv:192.168.1.137
802.1Q: auto
VLAN: 0

Router has a VPN between .2 and .1 networks.

I can see the phone request registration, but I never see a response back from the IP office. It is almost like the MikroTik router will not pass h.323 both directions.

I moved the Kentrox router over, killed the bridge in the MikroTik, put a new static address on the Kentrox. Now the Kentrox routers are handling the VPN and it works great. I just didn't want another router in the mix.

Any help is appreciated.

Something is blocking it so itmust be a setting on the MikroTik

sounds like ports are blocked

Port 1719 - Response to a VoIP device registering with IPo

Port 1720 - Data to a registered VoIP device
