manually open communication ports

flodis79

I have a VoIP box, and it's only blinking and blinking.
I would like to check if the communication ports are open
properly, and if not, open them.

How to do it in a Netopia wireless router? Cannot find
the menu option.

I need to open 5060-5061 UDP, 3478-3479 UDP, 10000-10007 UDP.

Thanks!

Try checking those port ranges using the "Shields Up" website (https://grc.com/x/ne.dll?bh0bkyd2 - what a horrible link). If they show up as stealthed, the odds are they aren't forwarded right. If they show up as closed/open, then they're probably forwarded right.

Thanks! I checked the STUN capacity with WinSTUN and
saw that VoIP will not work on my symmetric line. Does this
mean that Eircom doesnt support VoIP??

What internal ip should i use in the pinhole menu? The one of the router,
ie 192.168.1.254? Or the one i got from the voip box (i got 192.168.1.13).

And what about internal port? Just leave the zero?

Chalk

for the ip use the voip box
for the internal port use the number of the port your opening.

Thanks Chalk and everybody! just got it working now!
Approx how is the download from the voip per minute if
i have "gsm quality" preset for the calls?

Chalk

probably negligible,

just get the bitrate ,say 128kbps

multiply by 60 [seconds] then 60 again [minutes] and youll see how much nandwith it takes per hour
128 x 60 x 60 = 460800kilobits

divide by 8 to get kilobytes so 57600, divide by 1024 for megs = 56 megs for a 1 hour call at a very high bitrate,
gsm could be about 16 - 24 kbps so an eight of that again


sorry if its not clear but it should be correct [ i hope :rolleyes:]

GSM seems to be about 11-13.3kbps. So roughly 1/10 of what was previously calculated should be accurate.

Thanks for these calculations!
Could you pls clarify how much this will be in MB per hour if 128kbps
bitrate?
Is the download stream the same all the time, ie also if both parts are
silent?

at 128kbps, the codec needs 56megs an hour (thats upload i assume). However GSM is between 11 and 13.3kbps from my googling, so that means if you use GSM, you'll need about 1 tenth of that figure, which is about 5.6megs an hour.

Best thing is to double check with your provider though
