Call Admission control

[Fraser Reid]

Hi All !

I have a problem , I am trying for the Gateways & Gatekeepers exam.

My problem is that there are 2 different answers to my question in the Cisco Press Book.

It is about controlling the bandwidth needed for calls

say a call would need 64k (ignore headers and other stuff for now)

should I configure double the bandwidth for a session ?ie

bandwidth session zone localcall 128

or leave it at 64k

then there is the interzone.....

do I also need to double the bandwidth there too per allowed call ? ie

bandwidth interzone zone localcall 256

for 2 allowed calls ?

Bandwidth requirement also depends on the payload size.

Yes I know that , I am just looking for clarification to what "value" the above commands should have.

Hi

if its G.711 then it shud be 80 Kbps per call sof ro 2 calls it shud be 160 Kbps

For G.729 it takes 24Kbps so for 2 calls it shud be 48 Kbps

Hpe this helps

Hi,

up to my knowledge you always need to double the bandwidth when configuring GK.

let's say you have one call G711=80k

in the config:

bandwidth session zone localcall 160

or

bandwidth interzone zone localcall 160

Good luck with your exam
