Well the real question is what are you looking for. Are you trying to have a voip installed into your network so that you can make calls across the internet or your wan. Or is this VOIP network for a single location.

You need to give us a little more detail as to what your looking for.

hi,

I will give full details. our customer having nearly 20 branches are connected to central office via leased lines.

And some branches are connected by internet.

Now customer willing to use voip on all these branches.

That is From central office to leased line offices and internet offices vice versa..

And one more thing, there are analog phones with PBXs.

That is good but there are still a lot unknown here,

what protocols the PBXs support,how many people in the branches?

You can use cisco call manager at the central site, and voice gateways like 2811 voice bundle+SRST, with the needed WIC module to connect to the PBXs.

The answer is general as the question.
