Configure Trixbox with Comcast Digital Voice
Submitted by Zoren on Mon, 03/26/2007 - 10:10am.
I wanted to ask for some advice and direction. I have done a lot of reading and haven't found what I'm looking for. I am interested in using Trixbox with Comcast Digital Voice service. I am rebuilding a laptop to load trixbox on. The Comcast service uses their own network for voice traffic. It comes to my house through the cable line into an arris emta which then connects a telephone line into a traditional jack. This activates all of the phone jacks in the house. It has one rj45 port to the phone jacks and one cat 5 network port. There is some sort of conversion taking place in the emta but I don't think I can configure it directly. I want to put Trixbox on the laptop and use it with the Comcast service. I have two phone numbers. I want one to plug into a phone in the house and one to forward to my cell phone. Can this be done? If so, do I need additional hardware?
Thanks in advance for taking the time to read my query.

Zoren
You will need a FXO card.

You will need a FXO card. ...and I haven't seen an external one yet...so you'll have to use a desktop, instead of a laptop. But even then it's a messy solution. Why not dump Comcrap and just get yourself a SIP trunk from your friendly neighborhood BYOD provider?
...and by two numbers, if you mean a "distinctive ring" number from Comcast, that won't work. Comcast won't pass DNIS, which you'll need for routing to separate destinations.
Grandstream has cheap

Grandstream has cheap "handytone" FXS/FXO external devices - they can be gotten on ebay for abour 40-60.00 so you are not out allot of cash in the event it does not work - they'll run cordless phones and all landlines phones of the like - I'm not sure about the conversion but the handytones also have a RJ45 jack and speak across the network.
Again save the cash and try one and you'll likely figure it out with the laptop/handytone without going through to much trouble.
Best of luck!
NOTE: on the handytone - make sure it has both FXS/FXO the part number to search for is "handy tone 488" Do not purchase "unlocked" pay if needed 10.00 more for a new one that does not require the BS.
Thanks everyone for your

Thanks everyone for your replies. I will look into your suggestions. I was able to load trixbox on the laptop and will continue to work on it. Looks great so far. Comcast is great as a residential service. Private network with great sound and reliability. I am just having trouble wrapping my mind around the conversion that takes place between the emta converting the voip to the phone lines. Maybe I can setup a softphone and forward a line to my cell phone.
Thanks again,

I am an installer for comcast (i know i know... everyone hates them) but I do a lot of phone installs, basically the EMTA takes the RF signal from the cable and locks onto a frequency that carries the phone call all the way back to the HEAD-END in your area. The EMTA provides the dialtone and conversion from voice to data packets to send just like any other data to the switch at the HEAD-END where it interfaces with other PSTN's. There are 5 ports on the emta's:
1 RJ45 Ethernet link (for internet only, so you don't have to have a seperate modem)
2 RJ11 Phone jacks (1 for line1/line2, and 1 for line 2 only)
1 USB Type A Port (for use of the internal USB->Ethernet adapter, again for internet only)
1 Power plug
If all you want one of the numbers to do is forward right to your cell phone, then you should just setup call forwarding on the line (*72
I have trixbox on 1 POTS line and 1 CDV (comcast digital voice) line right now, the CDV lines is actually lots clearer and lots LESS echo than the POTS line.
hope the information helps someone out there.

Which under the tech specs support sip or PacketCable .. So I don't think there is some kinda magical technology behind it as the sales people would like you to believe it is still just voip..
PacketCable & Session Initiation Protocol Support
All Touchstone Telephony Modems support PacketCable (NCS) and Session Initiation Protocol (SIP) protocols. Both signaling protocols are based on the same architecture which allows ARRIS to maintain similar capabilities between software loads (i.e., provisioning, management, web interface). In addition, the available SIP signaling software provides Quality of Service (QoS) consistent with PacketCable Multimedia QoS methods.
We have a couple different

We have a couple different accounts with Voicepulse and Vitelity .. we needed 3-4 channels unlimited for our auto dialer. I haven't found any all you can eat VoIP providers that don't have a stipulation about autodialers. Comcast didn't have any stipulations in the terms or the contract about that so we got some lines from them. Plus it doesn't effect out in office bandwidth.
That's a great reason, I am

That's a great reason, I am surprised they don't have that stipulation.
It is interesting how Comcast and Time Warner have moved the residential Packetcable voice offering into the business space by simply repackaging it from a marketing perspective.

Doh I take that back

I take that back..
Though the sales people assured me auto dialing was total cool and no problem..
On the order contract in .5 point font it listed 3 other documents which I was agreeing too..
Which you can not find directly on there sites.. You have to manually type in the addresses..
So you get to the "BUSINESS SERVICES CUSTOMER TERMS AND CONDITIONS" and there it is on page Article 17.1 Additional use restrictions. If we deem you use our service too much we can terminate your account without notice. or modify voice immediately ?? whatever that means?
So that sucks. It would be sweet if I was told that before signing up and had the info public listed on there website.
I don't know of a provider
