SV: SV: [Asterisk-Users] Cisco and "protocol application invalid"

[Bjørn Ove Kristiansen]

Thanks for the suggestions everyone!

The thing is, when I run tcpdump, this phone never really requests anything
as far as I can see.

The IP-address serving is not handled by the Asterisk box, which is on its
dedicated IP-address, but by a consumer type SMC Barricade 4-port router.
There's no option to define boot tftp on this device.

I'm thinking of getting myself a console cable for the phone, and see if I'm
able to log in and set the variables using that. Don't know if these cables
can be purchased in stores or if they'll have to be hand made..

My biggest problem is that I simply do not know which IP-address the phone
is searching for - if its searching for any IP address at all.

Thanks again, have a great weekend.

Bjorn

Bjorn,

The phone will use whatever TFTP server your DHCP server tells it to  
use. That is what the above line "option tftp-boot-server" is  
supposed to do, it tells your DHCP server what address to give your  
phone. If your DHCP server does not give the phone an address, and  
you have not specified one manually through the phone's settings  
interface, then it will  (in my experience) default to the same  
address as your DHCP server.

What are you using for a DHCP server?

Can you enter the settings interface of the phone if you leave the  
ethernet disconnected? (If so, manually specify the TFTP server  
address.)
