Voice over IP Design Challenges

[Zargham Haider]

Dear All,

I am working in an organization where my next assignment is to design and implement VoIP in 16 locations (Different Cities). I am trying to design the project. i need some initial help how to think.

i have 16 locations and it should be 100 % Cisco solution.

any idea....

Start by reading SRND:

and Preferred Architecture

Do you have any voice background?  As to do it correctly and account for all design components and to do it correctly you'd probably need help on your first attempt.  Might be a good idea to consider reaching out to Cisco Collaboration partner, at minimum they can provide FREE bill of materials and Statement of work.

Hi Chris,

Thanks for valuable reply... i do have VoIP background but my current job was not 100% VoIP. so i was out since 3 years. and now your provided links really helped me and i am again in. definitely i will contact Cisco partner but after covering my info gap...

and also thanks Dennis for you informative reply....

One consideration, among many others, Is, your WAN.

you will need to talk to your provider and make absolutely clear, that you will need to be able to run QoS over your WAN. to protect video and voice. This is not trivial.
