Hi, I'm trying to setup a Yealink IP phone. The phone registers and everything works. The only problem is very choppy sound quality - even when the phone is the only device connected to the router.
The Yealink comes with a built-in router. So I thought I would go that route and connect it directly to the cable modem. I tried that and the phone can't pull an IP address. I called Brighthouse to see if there was anything they could do. She reset the modem from her end. The phone still couldn't pull an IP. She then said that the modem isn't meant for VOIP and I would need to buy a modem/router combo.
Does that sound right? Can you not connect an IP phone directly to a cable modem? The Yealink's manual doesn't specify that one way or the other. With it acting as a router though, you would think it could. I read that Brighthouse has their issues with IP addresses and multiple devices and mac addresses. Are there special instructions I need to give the Brighthouse rep - to get the phone to pull an IP address?
I ran a line quality test and everything passed: »/pingtest/572b ··· /2976042
. It's standard Roadrunner service. The equipment is about 7 years old:
Modem: Toshiba PCX2500
Router: Belkin F5D8230-4
Any suggestions are appreciated. Thanks!
