Hello All,
I hope this is the correct forum for this question, if not Im sorry.
I would like to use the Cisco IP Phone 7960G. If I plan on only having two of these phones what else will I need to get it going? I have not been able to find a VoIP service provider for a small systems. Any link or advice would be appreciated.
Thanks
 
If you just want to make calls from one phone to another you could use the CallManager simulator... that handle assigning a number to each phone and initiating calls.
 
No Im looking to replace my Phone system and switch to IP for all incoming and outgoing calls. I currently have a Cisco 2514 router and a cable connection of 384/3.0Mbs.
 
You could easily run a small network on a 2610XM using call manager express and Unity express. You could even run the DSL connection on it also. I just got my first express router setup and it is VERY cool. I believe the 2610XM (must have XM on the end) can handle up to 24 phones and 48 lines.

On the other hand, you could go with a managed service, but I think you would be better off handling it yourself. It will free if your limited bandwidth on your DSL connection and allow you to add and delete phones quite easily. It seems more complicated than it really is.

Cisco Call Manager Express
Cisco Unity Express

Cisco Unity Express comes standard with a 12 user license and a very limited auto attendant. Most people here can help you out and they could even set it up for you (for a small fee I am sure).

So If I understand this right, All I need to make this work would be a

Cisco 79xx series phone
Cisco 2610Xm router
Call Manager Express
And Unity ?

I was looking at the Cisco 1750 Router with a Vic VoIP card installed. I think that router would be a little cheaper, but In not sure if it would work. Also what service provider are you guys using. I have been able to find very much information on VoIP service providers.

Thanks for your time and help
 
The 1750 will not work as a Cisco Callmanager Express server. It will work as a gateway though. Here is a link to the support platforms. The 1751-V is the smallest router that is supported.



The 3640 and 3660 are also suported, but not listed. It takes a couple days of reading and little but of practice to get the whole thing working. Cisco Callmanager express is included in the IOS of the router and requires no extra software. There are some web pages that can be added to make allow GUI configuration, but doesn't contain everything. The product ordering guide is here. Looks like up to 24 phones retails for 750, but I am sure you can pick this up for much cheaper. No one pays full retail anymore. The best deals I am able to find online are at

This is really an inexpensive way to get a very simple and scalable phone system with a good name attached to it.


It is what it is!!

I forgot to mention that I prefer to buy used hardware and bring it under support. Typically you can get it much cheaper.

Thanks for all your help, yuou have been very helpful. Quick question, If I use the 1751-v and connect that to the internet, will me phones plug into that? And should I use a QoS enabled Cisco switch as well? By the way I found the router for 499.00. I now need to find a service provider.
 
I hope by service provider you don't mean a VoIP service provider. Teh 1751-V will be your PBX. All you would need is a few phone lines or a T1/PRi for incoming calls. Keep in mind that you need 1 DSP resource for every concurrent call you make. So if you have 4 analog lines coming into the 1751-V, you will need 4 DSPs to convert the analog voice to SCCP.

Ahhh ok, I get it now. So if I was to purchase a Cisco 1751-v and had analog phone lines to connect to it, I would need a DSP module correct? I thought I needed a FXO module instead.
 
An FXO module is an interface. It can be used for dial in/out in addition to voice communications. If you are going to convert the analog t VoIP, then you need a Digital Sound Processor (DSP) for each concurrent voice call. So if you have an FXO VWIC, you will need 2 DSP modules to to use both of them. If you only use one for voice and one for something else, then you only need 1 DSP. If you have a T1 (24 channels), then you need 24 DSPs to use the whole thing. In addition, you can use DSPs for a few other things also.

Transcoder - Changing one compressin type to another. If you deploy Cisco Conference Connection then it only support G711. If you have sites that use G729 for your cisco phones, then you will need transcoder resources to convert the G729 to G711.
Conferencing - You can use DSP resources to act as a conferenc bridge. If you deploy callmanager express, then this is really your only choice. If you deploy callmanager on an Win2K server, then it can do some conferencing. I usually suggest that you have at least 6 DSPs more than you think you need. DSP resources are a bit expensive depending on the platform you are using, but are vital for those "must have" features that come up after the initial deployment.


So to reiterate the above, you n eed 2 thhings. A method for calls to come in and a DSPs to encode the voice traffic to IP.


It is what it is!!
