VOIP network design

Hi,

my name is monsour and i have CCVP certification but i have some difficulty in Designing part for voip network i know the important configuration i have read books and watched videos about R&S &Voice

here is an example of problems i am having.

A client want to have cisco ip phone in 3 branches connected togather each branch has 50 ip phone and 10 ip phones for outside dialing to pstn .the problem is what do i need to design it including the voip gateway model number ,the cards i need to install in the gateway (to allow for outside dialing not fxo ) and where i can install the CME in the same voip gateway or other knowing that the client will use VPN for connecting between branches .

please include the Voip gateway model number , connection type (maybe isdn,BRI,FXO T,E lines),and other router we may need .

also if there is any book or video  i can use to learn more and dig deep please let me know .

Thanks in advance

Re: VOIP network design

Dear Mansour,

As Jamie told you will not get an answer to your question like this. If you are a partner try reaching Cisco partner helpline where you just need to tell your requirement to pre sales team and they will assist you.

For now I can give a rough design. As you told that you have multi sites and each site with 50 users then go for Cisco BE6K and two 2921 routers with SRST licences.

Let us say that you have a HQ, BR1 & BR2

Then in HQ go with BE6K along with a voice gateway as per your requirement.
See you should do the sizing as per the BHCA.

Go with 2921 along with 50 STST licenses for branches.

Mate, please check the CCVP documentation on Multi site voip designs and clustering options or check the SRND.

Please do some research first and put some concrete questions after you have done that,  this forum is not intended to do your work for you.

Thank you for the reply,

But i have searched in the documentations it is not mentioned which Gateway to use it's generally speacking i know the design generally but what i was asking for that i need the VOIP gateway specification like how many simualtaneous calls it can proceed and if it has the E,T line port and so on

Can you please give the book name or where to go.

Thanks

Your ID says you're a guest user, if you were a partner, you could reach pre-sales so they could build the BOM for you, I'd recommend you to engage a partner so they could quote the solution for you with all you need regarding PNs and what to buy. You're not going to find that in any book.

You should know what type of connection would work best based on your requirements and availbility in your area. Also, how many users and what you need.

How many users/devices a platform can support is in the CME compatiblity matrix, CME is all up to the IOS and license, which modules you can use, you may use the DSP calc to also size requirements.

What you're looking is pretty much training for sales, so review here:
