Port forwarding...
shakey:
I have been having issues of dropped calls (i.e. the people I call can hear me, but I can't hear them at times). Additionally, after hanging up, I have to wait some amount of time or reboot the obi110 to get a line again. I am trying to use the obi110 with google voice and have an rv042 router. My connection speed is 3mpbs D/L and .77mbps U/L (speedtest.net). Additionally I have a vpn tunnel active, but even when I disconnect from the tunnel the same thing happens. I noticed that people who use vonage and have the same router have a method to address this with port forwarding. The link can be found here: http://portforward.com/english/routers/port_forwarding/Linksys/RV082/Vonage.htm My question is, what are the ports that the obi110 uses- based on the above, is it just a range for UDP that I should forward to a static LAN IP for the obi110? If so, what are the ranges? Thanks!

I believe that the SIP accounts use the following UDP ports:
5060 and what ever port you have assgined the the following section of the Obi web page setup:
Service Providers->ITSP Profile A (an B)->RTP->LocalPortMin
Service Providers->ITSP Profile A (an B)->RTP->LocalPortMax
These port numbers can be changed.
I believe Google voice uses 5222 UDP
The Obi service uses other port numbers I think. The Obi-Guru should answer that one.

Thanks for your response!
I tried what you said and gave somewhat more generous ranges for values and it works a bit. The difference is that now when I access my computer at the same time (just to refresh this page for instance), I lose the connection- that is, the person I called can hear me, but I cannot hear them. I was told to disable the firewall on my router, but this doesn't give any success. I will wait for Obihai to get back to me on the ports they use.

One thing you could try, if you know how, is to put your OBi in your router's DMZ (essentially allowing it unfettered access to the Internet). You can only do that with one device in your local network, but sometimes it helps.
Just out of curiosity, do you use DSL for your broadband connection, and if so, is there any chance your DSL modem has a built-in router? Many DSL routers do, and when you put another router behind the DSL modem it can cause "double NAT" issues for SIP connections. Putting your device in your router's DMZ might avoid that issue, although there may be security implications that I'm unaware of in doing that.

I tried to use the DMZ and still an issue. As I mentioned before, this only happens when I am trying to access the internet from another device. I am using a cable modem without router so I don't think that is the case. My router (RV042) has the ability to prioritize interfaces, so I created a googlevoice (UDP ports 5000-5500) and Obi (UDP ports 16600-16900) both download and set them to high priority. I don't know how to prioritize the tcp ports, but I think I should set them high because conversations get choppy if I access google's search engine and do a simple search- it cuts the conversation for a moment.
