I would like to share my experience about remote SIP extension with Trixbox. It looks like hundreds people have such problem over and over again, and it is like the worst nightmare when you try to use remote IP phone from your home (for example) and you hear dial tone but no audio ...... Yeap I can feel your pain becasue I have experienced the same feeling. I have spend 3 days dealing with no audio on remote SIP extension. I used Polycom IP 501 but I think it does not matter what phone you use.
I shaked my firewall when Trixbox was installed, and no luck. Then I have tried to kill Polycom phone .... , and finally get to a router that is at my home. SIP was conected with Trixbox (however TRIXBOX 2.6.2.3 showed 1058 SIP port openned, not 5060 like other phones inside the LAN where TRixbox was placed) and of course all the time there was no AUDIO. I could dial from any extension to remote extension and hear audio but not vice versa. I have started to suspect my home router and that was the problem that lately shows up. I simply hooked up PIX router and was able to hear audio when make a call from remote to internall extension. I don't want to blame ISP beasue everyone knows that RTP ports are in charge of audio. Of course I was playing with forwarding ports on previous router but no luck .... I think cheap routers are the best idea when you think about remote SIP extension. More expensive investment would pay with less headache in setting up everythink. Of course someone would ask did you check your Trixbox config files yea yea yea ..... sip_nat and etc ..... That was my experience with remote extension and final conclusion IN MY SITUATION was that I used pretty cheap ($100) router that could not handle RIP udp ports ......

Remote SIP

Yes your completely correct that it is difficult with remote SIP extensions -- I have gotten it to work well and repeatable with pfSense -- So I use a DELL GX620 bookshelf PC with 2 NICs -- and bam.. the best routing solution as I have also gotten the QOS to work well. It is very fast routing - very configurable with great logging.

Just my two cents.

pfSense

Hi Jason-

I am pretty familar with pfSense. Could you share what how you configured pfSense/tribox to work with remote SIP extensions.

Thanks.

pfSense

Well honestly - I did a lot of reading and even more testing. There are several specific configurations via the web gui to make it work rather smooth. I manage 28 pfSense servers now - and pride myself on the configuration. There are settings I learned that even the pfSense team don't publish.

I have configuration differences also based on whether the client is hosted or premise server. This is because of the issue of multiple registrations via port 5060. and then specific settings for remote sip extensions.

I would rather not list those configurations but do offer paid support at very competitive pricing.

Another Option

Or you can buy the cheapest dLink router you can find. They work great for remote SIP deployments.

Normal store bought routers need not apply

This is not the case -- the thread was about remote sip -- they will give you one sided audio -- I am as cheap as the
next guy (reason I use open-source routing software) and they didn't work on the remote sip - infact, most won't work
either for multiple devices registering on the same port for SIP.. pfSense does !

Those routers don't have traffic shaping either -- now a firmware upgrade to DD-WRT on a Linksys router does a
descent job but tough to get working right.

pfSense

Jason, I understand that your knowledge is what you have to sell but this is a forum for sharing. You mention that you learn some of how you configured the pfSense from other sources. If you don't what to share your pfSense configurations, at least tell us where you found some of this info. It could help us in making some of the decisions on how to configure a pfSense.

Well As I was able to get

Well As I was able to get working Polycom501 behind DD-WRT with Trixbox behind Endian. DD-WRT is very easy and decent firmware when you compare to (example WRT54G Linksys crappy firmware). Endian is a little buggy, but I was able to get working 3 x PBXs with 4 SIP Trunks (different providers) and a lot of remote phones. Of course it did not happened in one or two days. It took me a couple of weeks to get piece by piece to work. Of course Trixbox forum was helpfull, as well as others. I can't say that about Endian's. But you can't require too much since you get free firewall software. AT this time I am fighting with pfsense. This is really nice piece of software and I say that my internal network is about 15-20% faster that I used it with Endian. The ONLY problem is I CAN'T get it work with remote extensions. I made a lot effort to read hundred of post. Apparently, most of them are different and every one is telling different story. I was able to set up all SIP trunks with providers and get both ways audio. Remote Polcyom501 was not able even register. Asstra 57i with the same pfsense configuration on both ends was able to ring but no audio at all. 20 times checked configuration did not bring positive results. yea yea I have checked that box STATIC PORT but pfsense send port 5060 using 50xxx
or something like that. I use fallowing scenario:

VOIP Phone-----pfsense-------WAN---------pfsense----------TRIXBOX

Ease enough to learn that problem is behind PFSEnse !!!!!!!!!!!!!! I know that or I can even smell that .... just kidding. A lot of features, but VOIP is still pain in the ass if you don't know THE TRICK. I was not lucky and did not find that trick that all is talking that pfsense is SIP friendly. I would say pfsense BETA 2.0 is more because at least it save a time with that NAT OUTBOUND but it is not stable so ....

If you can of course give away the trick about pfsense that would be appreciate, if not I would understand
totally - If you spend weeks to figure it out and someone else can get it in 5 min this is not always right.

This is my 5 cents. I will update this post when I figure it out how to get pfsense work with remote phone and Trixbox.

Well Firewall Optimization

Well Firewall Optimization Options should be set up as censervative and static port in Outbound manual NAT as YES. Thats all. There is no other settings in GUI at least that you can change it.
