Mitel Phone System behind a Meraki MX250
Not sure if this allowed or not, but im double posting this here and on /msp
We are the network provider for client where we have a Meraki end to end solution (MX/MS/MR)
The Mitel voice provider is installing a Mitel PBX - i believe this is a Mitel EX Controller (ive been told its a virtual within the physical device)
The provider is saying its not going to work behind a Meraki because they need SIP ALG, this is the complete opposite of what we have been told from other Mitel providers, where we are asked to disable it (which we cant anyway because the MX doesnt do SIP-ALG)
Further to this, we have other clients supported by different Mitel providers which use the same back end network (supported by us) which is the same Firewall and switches with an ax3000 Mitel controller
So my questions i suppose are:
- Why do they need SIP-ALG - and is it infact a requirement?
- Are the EX and AX fundamentatlly different?
I want to get this phone system working, but the provider is just passing the book, saying its not possible and they need to put in their own router (which the client doesnt want to pay for) and also has other implications in that the wider solution on other sites would eventually move to this Meraki model.

Anyone out there using Mitel phones and dhcp options to get them pointed to the right server?
Our team mainly just hardcodes the call servers into the phones, but I've been asked to look into using DHCP and option 43.
I found a mitel string option 43 but it doesn't seem to work.
i'm using DHCP server on a L3 switch, if it helps.
