need your kind help ?!

hi there,,

I am a communication engineer i realy need you kind help?!!in my orgnaization around 160 employees and we are going to move to a new building & i am planning for ip telephony system please provide me what kind hardware & software i need to build my cisco ip telephony, i have tow cisco router 1700 & 1800 will this compatible for ip telephony ? plz help me with your kind advice ..

Re: need your kind help ?!

Hi Khalil,

You will need to a have the following:

1- 3560-48-POE

this will be the access switches which will power your IP phones and connect your LAN,

You can connect then your PCs behind the IP phones which hace a port to the switch and another to the PC

Each switch is 48 port

So consider your needs.

2- Call manager

You can check on cisco which version will fit you needs

you can check this link

3- also it is better to have a 2821 router to act as your gateway

IT will support you having E1 to pstn and FXOs and FXSs and a unity express if needed

the ability to add PVDMs

It is the best one for this solution

For your 2-routers, please specify the exact models of them

Wish this be helpful :)

Re: need your kind help ?!

Hi Khalil,

You have three options for call control:

You could get a 3845 and support up to 250 users. The 1800 will not support anywhere near as many people as you need for CME. You could squeeze into a 3825 CME, as it supports up to 175 users.

You could get CUCMBE, this is CUCM/unity connection in one box.

You could buy a full CUCM cluster, along with Unity. (this is probably too large for 160 users)

For hardware you will need a voice gateway with a PRI. This means you will probably need at least 1-2 PVDM2-64 for DSPs, you may want a VIC-2FXO for 911 emergency access, and probably a VWIC-2MFT-T1 for a T1 access. You could put this into your 1800 or 1700 as long as they are a voice capable router (1861 and 1760-V).

You would need to look into something like a 2811 with a NME-CUE.

As well, you would need to get the IP phones, PoE capable switches, and the licensing for all the above.

I would contact a local sales contact, and they will be able to give you the full information on all of this.
