I am looking at different ideas for a portable 12v VOIP server. I have looked at a computer running on 12v to WRT54 and several other ways. I would like to have this system have the capability to be setup in the field and to run on battery power and maybe a small generator. If anyone has any ideas or is currently working on something, I am looking for ideas.

There is a version of asterik VOIP server that runs on the WRT.

It would be a huge win if we get that open source server running with open mesh!

Yes, it would be nice. Do you have a link to the software? I have been playing with PBX in a flash, but it needs a computer to run.

Try a Linksys NSLU2, aka SLUG.

I have been working on the email server side, so I  have not made to much progress. I have been looking at C3X because it does not require the "whole" computer to run the software.

Has anyone got 3CX working over HSMM-MESH "WITHOUT" doing just 1/5/13-DMZ nodes?

I just started into VoIPoM, and have 3CX on a XP-Pro box with its own 3CX softphone, a 3CX softphone on MY personal PC, and 1 grandstream adapter.

I got it all setup and working on the LAN, but then when I moved the ATA over behind a mesh node (my LAN is tied to my mesh), I can RING the ATA from the softphones, but get no audio either way. If I try to call either softphone from the ATA, I get a busy signal, even though all 3 show registered.

I have mapped numerous ports and ranges on both the LAN gateway and the node at the ATA, but same issue. I feel like im missing a port somewhere or something.

Any clues/hints/tricks?

One thing I am doing, (since Im just starting to build it) is when I create extensions, I am using the last 3 characters of a callsign to get the numbers -- k5KTF=583, kd5MFW=639, nG5V=458, etc-- so we shouldnt need a phone directory as long as you know their callsign. :-)

(I thought it was ingenious :p )

Any suggestions to fix the porting/etc is always appreciated.

Sounds like the RTP ports are being blocked somewhere.  TCP is used for the control channel, and UDP is used for the audio channel, using the RTP protocol.

There is a firewall somewhere blocking the ports (Usually 10000-20000/UDP).

However, you can also use the "VPN Free" feature of 3CX to make it a bit simpler.  It wont work with the ATA however (It'll work with the 3CX client softphone).

Here is my list of forwarded ports.

Now, yes, some are for other things (email, AGW/Winlink, IRC, etc) but from 5000 down is what I could find for VoIPoM.

80   to my webserver
25     \
110   to my POP3 email server
587    /
8000  AGW/Winlink packet station
6667  IRCd on localnode
2003  OLSR Dot Draw from localnode to "Visual Of A Mesh Node" topology page on this website
5000  3CX
5004  "
5060  "
5061  "
5090  "
5480  "
5482  "
5483  "
5485  "
5487  "
7000-7500  "
9000-9019  "
10000-20000  "

Seems like overkill, huh? :-) But you can see why it SHOULD be easier to do it this way than try and change from NAT to 1/5/13-DMZ, since this one node does multiple routing to my LAN and other stuff.

I have even tried listing that 3CX PC in the local DMZ pulldown.
