Siproxd setup, hmm, need to get my head around it…

[fribert]

Ok, so we have a public SIP account at our phone provider.
eg: 12345678@sip.viptel.dk with which the phones use a password

I want to use the siproxd to move my SIP phones behind the pfsense firewall, thus saving a couple of public IP's.

The phone I've been experimenting with is the SNOM softphone. I want to make sure this works before I move the actual phones.

First of I need to understand the settings in the package.
Inbound Interface: LAN
Outbound Interface: WAN

Correct?

Listening Port 5060
RTP enabled

Port range 7070-7089 -> created firewall rule to allow incoming traffic to WAN on these ports.

Do I need to set more up for the proxy?

On a public IP I must enter the following in the phone:
Name
Account (phonenumber: 12345678)
SIP Registrar (sip.viptel.dk)
Password

Should I change these somehow?

This doesn't work however.

I've created a DNS entry called sip.domain.dk which point to my firewall's LAN IP.
Should I change the SIP Registrar to this, or???

I hope someone can help me out on this…

Best regards
