Mitel 5212 Phones cant' connect to 3300ICP

[snoadmin]

Hi,

We have a remote site that is connected to our main site via a T-1. The Mitel 5212 phones connect to the 3300ICP with no problems. However, when we test with one of the phones to connect to our main site via the IPSec VPN, the phone displays error "L2&Boot download err". The phone was able to run the PING test successfully and we were able to PING the phone from a computer at the main site.

What else do we need to check?

Thanks for your help.

Try this:
Boot the phone while holding the 7 key.
Program the IP address of your 3300 as a "Teleworker Server".
Reboot phone.
As long as the phone gets an IP address - any address - and the packets can route over the VPN you should be good.

Thank you Ralph. We don't have the Teleworker software, would this matter?

Are you using Static settings or DHCP

I've seen your issue when the phone is assigned a static vlan but the priority is not set.

We are using Static IPs and we don't use VLANs.

Did you miss the TFTP server entry?

It should be the same as the PBX entry.

Minimum settings for the phone:
IPaddress
Gateway (If PBX on separate LAN)
PBX Address
TFTP Address

P.S. Unless this is a lab environment, you should use VLAN's. Otherwise you will have voice quality issues, no question.

Hi,

I contacted our phone support vendor. Their expert said that this may be related to the IPSec VPN not supporting packet size of 1522 bytes during the TFTP file transfer. I did a PING test, PING x.x.x.x -f -l 1472 and indeed got message that the packet needed to be fragmented. I really don't want to increase the MTU on the router. Is there a way to set the 3300ICP to send packets at a smaller size?

Thanks,

Just set the TFTP server IP to the local 3300 and the ICP address to the remote assuming both systems are running the same release.
