Has anyone been able to get this to work with a Mitel Phone system? It requires One Bye Data type and I am struggling to get the data converted to that. Just was wondering if I am alone on this!
Hi @BWC I need to get these options to the Mitel phones but I am not smart enough to get this converted to the One Bye Data the SonicWall requires. Any help you could provide would be greatly appreciated.
I had to use a web developer tool to bypass form validation to allow me to paste in a string. Works fine, but not "supported" and it confuses anyone who comes along later and needs to edit it :-D
I did raise a ticket with Support about what on earth this format is they're expecting it to be entered in. The response I got wasn't great, I was told you have to use a tool like this:
, then you have to put a semicolon between each one, and then, maybe, you need to always start with 0; and <length of string>; eg 0; 73; if the entire string is 73 bytes long. I never managed to get this working in the format that Support suggested and it was easier just to persist with the workaround I had found.
I think if Sonicwall insist on the string be formatted in a certain way, then they should provide a tool that can generate that format.
No idea if the workaround works with Gen 7.
I submitted an RFE but it never went anywhere.
Also, if you use LLDP-MED or CDP on your switches to tell the handset what the voice VLAN is, then you don't need the first-stage DHCP lease configuring on the Sonicwall. Handset tags its packets with VLAN 10, second DHCP request hits DHCP server on Mitel phone system, badda boom, badda bing, working.

Hi @CBack85 what do you need to send via DHCP Option 43? I did this a few times for different devices and it worked fine.
This is how I did it for elmeg as example. IIRC I created it as HEX and it got converted to DEC on the way, there was something weird going on.

id:ipphone.mitel.com;sw_tftp=192.168.1.130;call_srv=192.168.1.130;vlan=10;l2p=6;dscp=56;
So I got in Hex but no idea how to convert this.....

@CBack85 I don't know the format the Mitel Phone expecting via DHCP Option 43, but the string you mentioned (id:ipphone....) would be
0x69;0x64;0x3a;0x69;0x70;0x70;0x68;0x6f;0x6e;0x65;0x2e;0x6d;0x69;0x74;0x65;0x6c;0x2e;0x63;0x6f;0x6d;0x3b;0x73;0x77;0x5f;0x74;0x66;0x74;0x70;0x3d;0x31;0x39;0x32;0x2e;0x31;0x36;0x38;0x2e;0x31;0x2e;0x31;0x33;0x30;0x3b;0x63;0x61;0x6c;0x6c;0x5f;0x73;0x72;0x76;0x3d;0x31;0x39;0x32;0x2e;0x31;0x36;0x38;0x2e;0x31;0x2e;0x31;0x33;0x30;0x3b;0x76;0x6c;0x61;0x6e;0x3d;0x31;0x30;0x3b;0x6c;0x32;0x70;0x3d;0x36;0x3b;0x64;0x73;0x63;0x70;0x3d;0x35;0x36;0x3b
