[SR-Users] Kamailio IMS_QOS

[Ivailo Dobrev]

Hi Franz,

There no real OS PCRF. Yota/Telexir use to had some free VM image that 
is OK for test. You can search about FreePCRF. It is a little tricky to 
configure it but ... I made for my tests a really dummy one based on 
FreeDIAMETER. Generally speaking PCRF is the "brain" of the network and 
you should understand and design things well there. I have experience 
also w/ commercial PCRFs and there is no real answer yes this is a right 
way of making something.

Cheers,

Ivo
