I always get confused / use firewall / router rules so infrequently that I don't know what the right way to set these things up.
Can you help?
I have a VOIP service using a Grandstream HT-502 V1.2A gadget. The call quality isn't always good. That device is plugged directly into one of the ports on an actiontec router (left over from when we had verizon fios, but now we have cable internet 15down / 5 up speed.
I have lots of other devices plugged into a gig network switch in the basement that might be using the internet at the same time as the calls? That gig network switch has 1 cable going over to the actiontec also (so there's only 2 cables on the lan side of the router).
To improve call quality, that's a job for QoS, right?
The attached picture is what I did in the actiontec router. The grandstream has the ip of 192.168.1.52
But then i thought, should this be on the Ethernet/Coax or Broadband Connection (Ethernet/Coax) sections? Did I at least get outbound rather than inbound correct?
But that just gets the call out of the house with highest priority. Once it's on the web, it's fighting with all kinds of data / can't prioritize it, right?
Does the VOIP provider have any bearing on the quality of the calls? Iwe are using VOIPO.com). is there a way to substantiate / test where the poor qiuality - dropped fractions of a second in the conversation, etc. NO stuttering, max headroom type things. Just a m ssing sound here and there.
And most pressing, we have a house alarm service that uses the VOIP line. I know - that's not as good as copper / POTS. but it was working OK for months. now, they say their system is saying calls are coming in garbled / it calls 10s of times because they can't handshake.
I at least want to try to the QoS. Or any other suggestions you have, short of getting a copper / pots line.
