Yes, an IT question as I know there are many IT guys here.
Have to do something with my VOIP phone, the poor quality is driving me crazy. This is my home network, single router, and my home VOIP phone in question.
There's 2 techniques mentioned on the web, one is putting the VOIP modem inside a DMZ, and the other is setting up port forwarding in the router. A little debate as to which is better.
Anybody? TIA

Why isolation? Isn't the DMZ to make sure the router doesn't interfere with any VOIP packets coming or going?
No I'm not sure my system is the problem, but as this is my 3rd VOIP provider over many years I know if I phone they will just tell me to make a DMZ.
Is the VoIP server hardwired (good quality RJ45 terminated cable) to the router?
With the VoIP server hardwired to the router, have you tried a corded phone attached directly to the VoIP server?
That is how you can establish a base line setup to address the issues you are experiencing. Any wireless connection may be suffering from band congestion in your area.

I've been through all that kind of stuff over the years. I use VOIP wired to the hardlines in the house. I really am looking at the narrow question I asked.
DMZ is definitely the way to go. Then your VoIP phone will get a provider allocated address, quasi direct internet connection. On the other hand, port forwarding is behind a NAT, meaning your router has to translate from private to public addresses. More work to the router, potential quality issues.
If your phone set is wireless, make sure it is not the source of your problem (as it has been already advised).
