Anyone using 2 or more lines with m0n0wall or pfSense router ?

I don't know if support has tried this already, but I'm curious if assigning different SIP servers to the ATA's would alleviate the problem. Maybe the SIP communication will properly traverse the firewall to the correct ATA if the SIP information is coming from different SIP server IP's. The data is either being blocked or being routed to the wrong ATA.

1st ATA - sip-east01.voipwelcome.com (Washington DC)
2nd ATA - sip-central01.voipwelcome.com (Dallas)

Hi tritch:

Thank you for your post.

I did post on another thread about possibly using one ATA. That was when I thought that might be my only solution. That was when I thought my problem was port forwarding. Now I don't think it is a port forwarding issue because...

1. When I installed my Linksys router my two VoIPo phones are working quite well now. And there is no port forwarding set up in my Linksys that I could find...not even with UPnP.
2. chpalmer has a pfSense router with two ATAs and he isn't using port forwarding.
3. There is a pfSense link that chpalmer posted that recognizes that there can be VoIP problems if pfSense isn't configured correctly. Which means some smart pfSense router guru out there wrote up that configuration info for people who have VoIP connectivitiy problems.

I like the features that m0n0wall and pfSense has. For instance I have a seperate firewalled WISP subnet on my m0n0wall, seperate from my home network. Now with my Linksys I have to run the WISP network along with my home network. I prefer not to do that for very long.

I will probably try upgrading to a later version of m0n0wall, just in case I have a bug in the version I'm using now. But I'm also thinking of moving over to pfSense. Especially since chpalmer is having such success with it.

I'm looking into taking a seminar on pfSense when one is offered in the USA. I'm on an email list now to be notified when one is offered.

You are right. The commercial Linksys router did fix my problem. Both ATAs are now working. But I will probably be testing out a newer version of m0n0wall to see if that fixes the problem. I don't want to give up on finding a root cause answer to the problem. For instance, I will see if I can interpret the logs that are generated. Someone on the other thread suggested that I can probably see what is being blocked by viewing my firewall logs and that can probably give me an idea of the root cause of the problem.

I will probably eventually switch to pfSense, since I know it works for chpalmer. Thanks for your suggestions.

One big reason I went with VoIPo is I know they are associated with HostGator, and I like the HostGator service. When I get to where I feel pretty confident with using router configurations with this VoIP service, I have even thought of reselling VoIPo service, since I think it is a good value for the money.

Hi guys:
Today I finally got around to loading a newer m0n0wall firmware version...v 1.33. Yipee...it worked.

The old firmware version was the culprit.

Now I can answer the one VoIPo phone when it's called...all without port forwarding.

I still have an old lingering problem with one way audio when one VoIPo phone calls the other VoIPo phone...only when my m0n0wall router is used. It's a problem caused by my router.

If I use the Linksys router I have two way audio just like I should. So there is some kind of an issue in m0n0wall causing one way audio, but thats not a big deal since no one ever calls me thats using a VoIPo phone.

So I thank everybody for the great posts and help.

That just saved me. That did it for me as well!
