VoIP phones behind Opnsense

[idscomm]

Hello,

Just switched from the other sense and I’m trying to figure out how to configure my 2 IP phones. I have a VLAN for the VoIP phones (2 devices), I have a NAT rule and can make 1 phone work but not both. I created an Alias but I don’t think I can NAT to 2 different IPs …

I tried the SIP proxy since I was using it on pfsense but it doesn’t work as well ….. doesn’t work at all I should say.

Anyone managed to configure more than 1 VoIP phone behind Opnsense? I am not using a PBX, each phone registered online through my VoIP provider.

Any input appreciated.

Thanks!!

How many public IP addresses do you get from your ISP? Do your VoIP provider and ISP support IPv6? You need two inbound paths for calls to be routed.

I run FreePBX with six internal extensions plus Lenny https://www.crosstalksolutions.com/howto-pwn-telemarketers-with-lenny/

The trunk to the VoIP does not have a concurrency limit on it, so all six phones can call simultaneously.

Yeah I thought about setting up a FreePBX as I used to have one but since I was running pfSense with the sip proxy and my 2 phones were working (I only have 1 public IP) I was hoping there was a solution for opnSense. I tried the sip proxy plug-in but it didn’t work … not sure if I misconfigured it or it was just not working … 

I guess I’ll have to see if I want to setup another FreePBX or simply return to pfSense
