From SRND
Configuration Recommendation
Because the initial reservation will be larger than the actual packet flow,
over-provisioning the RSVP and LLQ bandwidth is required to ensure that the
desired number of calls can complete. When provisioning the RSVP bandwidth
value for N calls, Cisco recommends that the Nth value be the worst-case
bandwidth to ensure that the Nth call gets admitted.3-65 Cisco Unified
Communications SRND (Based on Cisco Unified Communications Manager 7.x)
OL-16394-05 Chapter 3 Network Infrastructure WAN Infrastructure For example: •
To provision four G.729 streams: (3 ∗ 24) + 40 = 112 kbps • To provision four
G.711 streams: (3 ∗ 80) + 96 = 336 kbps • To provision four 384 kbps video
streams (G.729 audio) (3 ∗ (384 - 8) + 384) ∗ 1.07 = 1618 kbps • To provision
four 384 kbps video streams (G.711 audio) (3 ∗ (384 - 64) + 384) ∗ 1.07 = 1438
kbps

Subject: [OSL | CCIE_Voice] ip rsvp bandwith
Hi all:
For two g729 calls, how much band would you set at ip rsvp bandwith
These are the two options:
1: ip rsvp bandwith 64 (40 + 24)
or
2: ip rsvp bandwitn 80 (40 + 40)
The first one looks find becouse once the call is completed the rsvp bandwith
is reduced to 24 and a second call would be possible, but what happens if one
call is ringing and in this moment a second call arrives... then the second
call will be rejected due insufficient bandwith
This is way I would use the second option, and also if two calls are stablished
and a third call arrives rsvp will reject the third call (expected) 24+24 + 40
= 88 ; 88 < 80
What do you think?
