Making Outgoing call using GV - sometimes they can't hear me (FIXED)
emachac:
Making Outgoing calls using GV - sometimes they can't hear me (happens maybe once or twice a week). I end up having to reboot the OBi110 and everything works just fine. I've noticed it both ways - direct and speed dialing.
I am at the latest rev - using a Cisco E4200 router (OBi is set to high QOS) - using a cable modem...
Any ideas?
RonR:
One-way audio problems are frequently due to Network Address Translation (NAT) problems in your router. The easiest way to eliminate your router is to temporarily connect your OBi directly to your cable modem and see if the problem goes away. If it does, then it's likely your router is at fault.
If your router is the culprit, sometimes forwarding SIP (5060 - 5061) and RTP (16600 - 16998) ports to your OBi will eliminate the problem.

RonR - thank you for the reply. It doesn't happen often enough to setup the 'direct connection' test.
But, I did the SIP and RTP port forwards as you suggested and we'll see how it goes! :-)

What do you do when you have 2 (two) Obi's behind 1 (one) router? :)

Test to see that it is, in fact, the router by forwarding the ports to one of the devices. If the audio problems magically go away for that device only, then sorry to say but you probably will need a new router. When you buy it, make sure you can return it if it doesn't solve the problem, just in case you get another one that doesn't handle NAT properly (most new routers do, but there may still be a few lemons on the shelves).
Don't forward any ports on the new router - both OBi devices should work fine. If by chance they don't, return that router and try a different model or brand.
On the plus side, if it's an older router, you'll probably get faster speeds on your local network after you replace it.
On our system we have a two OBi devices, a few older Linksys/Sipura devices, and an Asterisk server. The ports mentioned in RonR's post above are within the range that we forward to the Asterisk server. Yet all of the devices coexist happily behind one router (and some of them do connect to providers other than our Asterisk server that are not on our local network). I mention this only to say that if forwarding the ports to the OBi actually makes a difference, it's really time to start thinking about splurging for a new router, because a good router will keep the packets flowing smoothly even if you have to forward those ports to a different device or server.
