[Users] SIP Proxy - CAC

[Michel Bensoussan]

Hello,

I need to write a CAC (Call Admission Control) module for an 802.11 AP 
(Access Point).
The idea is to use a SIP Proxy to monitoring bandwith utilization, for 
example according to codec, and allow or disallow new sessions, 
depending on resources.
I'm thinking using OpenSER for this purpose.
On a first stage I want to install a SIP Proxy on the AP (embedded with 
OS Linux) and on a second stage adding the CAC feature.
There is many modules in OpenSER and I'm not sure which one I should use 
for a SIP Proxy.

I'm learning about SIP but my knowledge is limited (till last week I 
never heard about it).

Thank you for advising.

Regards,
Michel.
