Let me explain my existing environment
as follows :
- I have two 2801 routers with
C2801-SPSERVICESK9-M IOS
- Each router has Four-port FXS
connected to the phones
- The bandwidth between these routers
is 256 Kbps ( Leased Line )
My qouestions are as follows :
1. How many bandwidth are a call
comsumed ( per call ) ?
2. To ensure that the bandwidth of
VoIP is not excess the maximum
bandwidth of leased line. And to
ensure that the priority of VoIP
is always higher than the priority
Data. I will use RSVP and CBWFQ
with ip precedence. Are these
features suitable for the
situation ?
Thanks!! : )

hi
regarding bandwidth consumption it depends upon the kinda codec which you are gonna use up there.
ofcourse g.729 does uses minimal amount of bandwidth and also that get reflects in ur quality.
If you are gonna used some kinda RTP compression out there that can always reduce the packet length drastically to lesser size which will be easier as well u will be able to use the B/W effectively .
regarding the priority part you can always use up LLQ to have high priority for your VOICE traffic and deploy CBWFQ for your data traffic.
if u wanna have sample configs would suggest to do a search in cisco about the same ,if u need further assistance do revert..

g.711 requires 80kbps
g.729 requires 24kbps
LLQ is the way to go and is the recommended way to impliment QoS for VOIP these days.
