[cisco-voip] QoS for VOIP.

[Rich Dobry]

Karim,

 

I don't know your setup, but if you are using the Call Manager, CAC is
setup in the CM.  You give it locations for each device and the
bandwidth between locations reserved for phone calls.

Depending on your coded per call, it will deduct the BW (25k for g.729
and 80k for G.711 - as far as I know, even if you are using cRTP, which
will lower the actual BW, it still decrements the 25/80k) and once it is
out of available BW, the call gets rejected.

Hello, 

 

I am trying to do QoS for VOIP traffic. Successfully configured LLQ, LFI
and cRTP with MLPPP over virtual-template.

 

What I am trying to do now is limiting the number of calls according to
the bandwidth reserved for voice traffic. Can anyone help???

 

With the current situation, if the reserved bandwidth can give 4 calls
with good quality (taking into consideration that the rest of the
bandwidth is consumed for other types of traffic), the 5th call can be
started but with very bad quality. I am asking how can I avoid this 5th
call from the begining??? I didn't find CAC config. with LLQ.

 

 

 

Karim.
