Cisco IOS for Voice 5

[ndinc]

I have this IOS in my 2801 and I would like to know if this IOS can support Voice I.E. we will add FXS, FXO boards and POE switch for IP phone etc.

Communications Manager Express / Cisco Unity Express

c2801-entservices-mz.124-10.bin
Cisco IOS Software, 2801 Software (C2801-ENTSERVICES-M), Version 12.4(10), RELEASE SOFTWARE (fc1)

If not, then can you suggest another router to start building this solution?

Small office less then 16 IP phones needed.

Thanks in adavnce for you reply.

Thanks for your help

For the Callmanager you need the following IOS;

ipvoicek9

As for the Unity it is an added device;

That should be plenty of features to run a VoIP network.

So the hardware /software purchase list should be as follows;

Based on specs of the 2801 router listed above

1) WIC for Analog or PRI T1
2) Call Manager Express
3) Unity Express (add on for Exchange etc)
4) IP phones (7900 series?)
5) A POE Switch to run the IP Phones

Does this sound like a good "Grocery list".

Or should I scrap the list and buy a packaged solution, like a UC520 Express or another "turn key" solution.

I am trying to nail this down to present it to the primaries, I have to make sure i cover everything.





Thanks for your help

Here is another dumb question;

FXO or FXS?

that is the question..

I am reading that FXS provide
1) dail tone
2) battery current
3) ring voltage.

Im getting confused, we have an analog toshiba DK16 switch wiht 8 lines (single twisted pair each). Switch has been working for 12 years straight. We would like to plug int he existing 8 lines in two 4 port VIC modules wiht all the software to manage (above "Grocery list)..

Any help you be great.



We want to start building a Cisco VOIP Solution.

Thanks for your help

The difference between FXO and FXS... the quick and easy;

FXO - POTS lines from your carrier

FXS - Analog phones/fax machines


I would also recommend the 3750 PoE Switch.


What type of service will you have for your phone lines? PRI or POTS lines? If a PRI then you need to have a VWIC 1MFT probably if you will only have one PRI (23B + 1D channel) or you can use the FXO card if you will have just POTS lines from your local carrier coming in...

We will use the POTS lines until i can justify a PRI.

I have never wrote any config's for VOIP so it will be interesting. My experience is with classic routing / vlan and normal IOS stuff.

IS Call Manager Express an application or is it anotehr tool in the firmware? I have seen demos of a GUI web interface and I was curious if I need to purchase that as well.



Thanks for your help

 

[DallasBPF]

you can do it either GUI or config... I would recommend the config to start out with just so you know it, but you can do the GUI as well... There is a guide on setting up the CME out there on ciscopress.com and the ISBN is;


1-58713-176-5


Now it is very basic on setting up the CME, but it will get you going with where you need to be... I used it for some lab work I was doing and still use it to this day on occassion for reference...

Hope it helps!!

For a single office with 16 phones I can't imagine needing an extra thousand dollars on a 3750 switch, I'd suggest the 3560 or even a 2960 POE model.

Don't forget all the required feature licenses per user(phone + router). I can't remember if the 2801 has PVDMs or if you'll need them depending on your config, something to check though.

 

[jneiberger]

ndinc, have you ever done a voice deployment of any sort before? it appears to me from your questions that you may not have much experience with this. Are you going to be responsible for configuring and maintaining the voice system?

 

[ndinc]

jneiberger you are correct I have never install voice deployment. I am a data guy.

But I want to and any and all advice is helpful.

Thanks for your help

 

[jneiberger]

Honestly, I would suggest hiring a local reseller with experience in implementing small VoIP systems. VoIP systems are more complicated than you might think. There are lots and lots of little things that can go wrong. If you don't have a basic background in telephony *and* VoIP, I'd highly recommend finding something with that experience to lead this project. That would give you the opportunity to learn a lot without having the responsibility of making it work.

 

[ndinc]

Thanks, but I want to learn this and I will build it one way or another without outsourcing. This is the reason for the thread.

Looking for sources and advice.

Thanks for your help

 

[jneiberger]

I understand, believe me. But if end users are going to be relying on the dial tone you provide, you need to be prepared for whatever might happen. In addition to having a solid background in handling real-time applications on a data network, you need to understand the telephony side of the equation.

I've been down a similar path. I started out as a data guy who understood nothing about telephony. Now I do data, legacy voice and VoIP. It's very important to understand telephony before you dive into this. It's very easy to get tripped up.

 

[DallasBPF]

go to cbtnuggets and get the CVoice video... it will help get you started and a good idea of the topic.

I do have to agree with Jneiberger though, it is good to have someone come in that knows what they are doing and shows you how to install it and maintain it...

But if you are really wanting to do this on your own, I would recommend the cbtnugget CVoice video and the lab book I mentioned above (1-58713-176-5).

I will be building part of it on my network to beta test it prior to a production area. I have 3 class C and 10 megs of fiber to work with.

I have done similar work in the past with Linux, Exchange servers, SQL, Cisco routers and switches. I build it and fall on my face in a non production environment and down the road I become good at it. I have learned from reading and reverse engineering.

I am not super smart, but I don’t give up and it works for me.

If I could get a list of hardware and software to start it would be very helpful.

I will check out the video and I ordered (1-58713-176-5) lab on Cisco Press (Thank you). There are many other good books as well, any suggestions there?


Thanks for your help

Good advice from both of you.

Great PDF!



Thanks for your help

 

[jneiberger]

I second the suggestion to read the relevant SRNDs. They're superb documents. I would also recommend picking up a copy of Integrating Voice and Data Networks by Scott Keagy. It's an older Cisco Press book that is one of the best around.

I'd also recommend learning as much as possible about basic telephony. Don't listen to the Cisco marketing BS. Voice is not "just another application." People get kind of touchy about having dial tone. They can handle not having network connectivity for a tiny bit, but all heck breaks loose when they don't have dial tone. People expect the dial tone to be there 100% of the time. You don't want to disappoint them.
