VoIP not working after modem replaced

Hi All,

Got "Triple Play" w TWCable. Things had been fine for 2 years.
Recently, would have to power cycle the modem (Arris Telephony) to get modem to work properly. Web pages were loading too slow. Ping responses were 2-2.5 seconds. Went down to TWC store, and swapped out the modem. Web pages loading normally, but the phone (VoIP) was not getting dial tone. Looked like they gave me a bad modem. Went back down, they gave me another cable modem. But, no fix. Internets fine, TV is fine, but no dial tone. Took a working phone, and jacked it straight into the modems tel.1 port. Phone lites up, but no dial tone.
Dont think both modems phone ports are bad.
What do you think? Is there a MAC address or something the cable company didnt register, which is causing this isue? I'm lost.
BTW TWC cant send a tech until Tuesday, 4.5 days w/o a phone.

Thanx all,

Joe D

It is possible they have your modem in an internet only class- I would call them and verify the modem is in a class avaiable for phone.

Comcast is my service provider and I have had an RCA DCM 245R modem for almost 10 years. Until recently it has worked fine. On an ever increasing basis I am losing internet connection and when I look at...


Hi,

It can be an issue with the modem or with the line. When the line drops the link then the modem shows only two lights. And, when you power cycle the modem (unplug and replug it) it establish the session again with the comcast.

So, i'll suggest you to get the line checked first and if comcast finds that line is working fine then get the modem replaced.

Shuts off...restarts, then runs for a few mins


If the modem is 10 years old then its time to replace it even if it was working fine if not very good to be abreast with the latest technology. The ISP must have tested the lines which must be fine because they keep on upgrading so you need to replace the modem to a latest model.

Telephone company installed Comtrend CT-301 modem. Recently having connection issues with computer and noticed RED alert light coming on frequently on modem. What is causing these problems?


I've seen bulging capacitors inside this modem causing me problems. Changed the caps and everything was OK for a couple of years after that. Started to have more problems with this modem recently, called phone company and sent me an new modem. Problem solved.
Also, it seems this old modem does not like the newer routers (D-Link DIR-615). It connected for a while, (30 seconds) then lost connection completely until power was cycled on model. The modem worked OK with older D-Link Router.

Have system for voip. Only can't hook up the


Try getting a router that has one in/4 out between modem n voip. Your voip unit should have an RJ45 connector to connect to router, not your computer. The USB connector might be to connect the voip to a different type of router, and will not be used. The 2 phone connectors are for two different phone lines that your voip provider can provide you with.

DSL loses signal during VOIP call.


hi,

i worked for verizon for two years and I encounter this problem many times,to tell you honestly,its not with you internet connection since if you'll notice,while you are connected to the internet and you make a call or call someone,its interrupted... Obviously,its the phone itslelf,the signal comng from the phone is different from the signal of the internet...thats the reason why you need a modem to convert the signal coming from the phone line to make it work for internet,,,what I suggest is you change the DSL plan from the Dry Loop to the regular dsl with the phone...

thanks and God Bless
