Here is the thread I post before ...

All sort of problem from Tomato. 

Also I can share you the experience.

1. If you unplug the power and restart the router . Phones never connect the server.
2. If you reboot from web interface . Then all phones start to work.
3. Etc .....

Here is another link http://www.dslreports.com/forum/r23423987-Equipment-Tomato-with-VOIP-warning

Google : Tomato + SIP issues

I am using dd-wrt for last four months never have any problem.FreeSWITCH default configuration working all the time.

That is my experience. Hope this may help you.

Thanks and regards,
Loyd

Brian,

Yes that correct. Sometimes Tomato suddenly send wrong messages to the sip server ... that causes authentication fails. We suspect the password strip off some characters. This is happen suddenly and after some time it will work back normal.

I try with 1.25 , 1.27 and 1.28  ..... no luck then I switch to dd-wrt all problems go away. I am using 
Firmware: DD-WRT v24-sp2 (08/07/10) voip

what is the Tomato firmware u r using?

Thanks
Lloyd

I had bad experience about dd-wrt, not stable on my router, always cause
the problem or hang up over night. I will try the nat-pmp on tomato.
Switch back to dd-wrt will be my last option.

BTW, how to disable extension register from external after I turn the
upnp up? All the extensions are in my LAN and I do see some ip trying to
register the extension from outside.

Thanks

Alex
