option#43 for mitel phones on cisco asa 5505

[kashif.ahmad837]

Hi all,

I have configured option #43 for mitel phone on cisco asa. but the phones are not getting the ip address from the dhcp.

this is the command on the asa

"dhcpd option 43 ascii id:ipphone.mitel.com;sw_tftp=64.28.118.9;call_srv=64.28.118.9;l2p=6v6s6;dscp=46v46v26"

this is the debug output on asa "debug dhcpd packet"

Hello,

as far as I remember, you need to configure option 60 (vendor-ID) as well on the ASA...

I did ant it is still not working.

Hello, 

can you add the Vlan identifier to your command (x is the Vlan number in which your phones are configured:

"dhcpd option 43 ascii id:ipphone.mitel.com;sw_tftp=64.28.118.9;call_srv=64.28.118.9;vlan=x;l2p=6v6s6;dscp=46v46v26"

I have tried it, still not working. I get the same msgs as before

Hello,

make sure the following ports are open on your ASA:

UDP: 69, 20001, 6004-6261, 50098-50508

TCP: 3998-3999, 6800-6802

Can you post the config of your ASA ?

[kashif.ahmad837]

Everything was good.

Only this command was missing

Switchport voice vlan dot1p

it is working now

Thank you guys for replying.
