My cable provider has installed a separate RCA DHG536 modem for my VoIP phone service alongside my SB5120 modem, and charges me $7 a month modem rental. I am upgrading the SB5120 to a DOC 3.0 modem and wonder if I can abandon the DHG536 modem?

I have a Windows 7 computer with Comcast HSI. It's a very fast computer, but the modem was really outdated. So was the router. So, we got a brand new Cisco N+ Router and a Motorola SURFboard SB6121 modem with DOCSIS 3.0 and IPv6. However, when plugged in, the new modem will not consistenly connect to the internet. We called Comcast and they tried to send an activation code to the modem with it connected to the computer directly, but it was intermittently going online, then offline, then back online, then offline. We exchanged the modem for an identical one, but it's doing the same thing, so the modem can't be at fault here. Comcast tried to tell us that something was wrong with our coaxial cable, but our old modem - a Motorola SURFboard 4100 running DOCSIS 1.1 - was working just fine with the same cable. Another technological "improvement" has failed me.
View 7 Replies View RelatedI have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?
Recently at my company we have started using Polycom i335 IP Phones from 8x8 inc, the thing is that while trying to use it directly through a switch it does not register with the server and I get a "url call is disabled" msg on the LCD of the Polycom. On that same switch I am using an Aastra 6755i IP phone, it is working absolutely fine, although it is using the same technology and ports.Now if I connect my laptop via wireless or if I connect a PC through wire and use ICS to share the internet and connect the Polycom to the shared Ethernet port, the Polycom works fine! On the same network Vonage works fine as well. but this Polycom only and only works via ICS?

I have the router for over two years, Present Firmware is V2.0.1.3, I have Polycom phone connected to the router using 8 x 8 VOIP service. The phone was working fine untill yesterday. 8 x 8 tech support suggested getting a different router. I have the same router at home and tried the same phone on my home router - it worked. So, the problem is not the phone but int he router. I tried to call Cisco tech support but found out that the warranty support expired and I need to buy a support plan. Called to buy the support, and gave up after an hours on hold. Left message.

View 1 Replies View RelatedWe've been configuring our swtichports as follows for our 7945 and 6941 type VoIP Phones, but are having problems witht the 6901.
VLANS
Vlan 900 is a VoIP VLAN
Vlan 999 is a NULL VLAN and is shut down:
interface g0/1
switchport access vlan 999 {VLAN to direct data traffic to the bit bucket becuase a PC shouldn't be connected to this port}
switchport mode access
switchport voice vlan 900
mls qos trust cos
spanning-tree portfast
The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.

solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?
im having this strange issue where everytime i plug in a voip phone to my 3550 the switch disconnects another voip phone.then to fix the disconnected phone (7940) i need to power off the phone 5-10 minutes then power it on again.
but the strange thing is, once i have to do that to fix the phone and connect the phone back to the switch, the port link is up, but no macs are seen on that port.
We have 2mbps leased line and have Cisco 1841 which is managed by our ISP. I have hooked up another 1841 (please find basic config below, it will get more complex lateron) Now when I connect my laptop I am able to browse Internet. But when I conect VOIP phone, it is not able to contact it's Hosted Server on Internet.
VOIP phone is Polycom SoundPoint 550 and I get URL call disabed message. If I try netgear Firewall everything seems to work.that the voip provider needs following ports UDP Range 16384 - 32766, TCP 5060 & UDP 5060. But in my config all outbound traffic is allowed. [code]

View 1 Replies View RelatedIf one has internet and phone service through Cable, I know you can buy your own modems and routers, but is there a particular kind of modem you'd need to get to support VOIP for the phone?
A friend of mine has phone through Cable and her internet and phone suddenly stopped working, although her TV service is fine. We are thinking that maybe the cable company's modem is bad, so she wants to buy her own modem, but we're not sure if it needs to be a particular type of modem. I've looked around for her, but haven't found anything in modem specs stating they support VOIP. Does it matter? Or can you buy any cable modem?
We already looked at the cable providers website to see their supported modems, but they are all the same brand as the one she has that doesn't work. She already has a wireless router, which she will plug into the modem she buys, so we're only looking for answers regaring a modem.
Life was great with my DIR-615 and Motorola Surf Board SB-5100 cable modem, but my D-Link refuses to recognize the Internet signal from the Thomson. The Comcast guy spent an hour trying to get it to work, but I'm stuck watching MLB.tv on a 24" monitor in a stiff office chair in my study, instead of on a 47" LCD in my living room. How can I force the DIR-615 to accept the Thomson ACG905? If you advise me to check settings or manually change them, please do not "assume" that I know how to access those settings.

View 1 Replies View RelatedMy Motorola SB6121 DOCSIS 3 modem is connected to a Medialink n-band router. Sometime in the morning (usually between 7am and 9am, the router loses the ability to see the modem. I can access the router's control panel, and I see 0.0.0.0 for WAN IP, Subnet Mask, and Gateway. Primary and Secondary DNS server are both blank. Connection Mode is Dynamic IP.I lose the ability to access the modem's control panel directly (192.168.100.1), even though the PC I use is hardwired to the router. So, I unplug the modem, unplug the router, wait, plug in the modem, plug in the router, and everything works again.I've had more than twelve service calls. Every Charter tech looks at the line, puts in boosters, takes out boosters, replaces splitters, and seems to only look at signal. I've BEGGED Charter to let me speak to an engineer, because my suspicion is that it's something to do with the DHCP server.
I did, by the way, replace EVERYTHING.I have had 5 different modems...same problem. I have had 5 different routers...same problem, including a modem/router combo.I've tried different brands, too.I've disconnected all wifi devices from the router, and rebuilt my PC's operating system. I've even unplugged the refrigerator, because one Charter tech claimed it was "upstream noise."I've been online only a few times when the system actually goes down. What I notice in the router logs is this: [code] So at 9:34, no ranging response - T3 timeout, followed by Unicast Ranging Received Abort Response;
then the Cable Modem Reboot due to T4 timeout, and the system time goes to 1/1/1970 at midnight. No ToD.
The last piece of information: Charter installed a second modem as a "test." That was originally in the same room. A month ago they did another line from the box directly to the test modem to skip the splitter on the house.That modem shows the same problems, EXCEPT -- not perfectly in sync. I might see the same error, but the time will be a few minutes and seconds off. And sometimes I'll see the errors, but the modem won't go down.Sometimes the first modem goes down, sometimes the second. I'm accustomed to a router "healing" itself when the modem goes down.It might be off for a bit, but then will re-establish. This Medialink doesn't do that. It forces a physical restart every day. There are other outages too, and all I get from Charter is "the signal strength is good."
