Often times complex configuration issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, its often difficult to do so for this type of issue.
As a matter of fact MLP (Multilink PPP) is the prefered way for running voice packets over load balanced T1s.
Do NOT do per-packet load balaning!
As far as QOS, you should use LLQ.
Define what protocols (netwoks, or specific IPaddress) you need to priorotize and the map it to class-maps which in turn shuold be maped to a policy-map.
By doing this you map ToS and CoS bits to needed packets, prioritize them and queue them.
Here's a sample:
ip address 0.0.0.0 255.255.255.252
service-policy output VoIP
ppp multilink fragment-delay 10
ppp multilink interleave
match ip rtp 16384 16383
match access-group 100
match access-group 122
set ip dscp 46
set ip dscp 26
access-list 100 permit ip any any precedence critical
access-list 100 permit ip any any dscp ef
access-list 122 permit tcp any any range 2000 2002
access-list 122 permit tcp any range 2000 2002 any
access-list 122 permit tcp any any eq 1720
access-list 122 permit tcp any eq 1720 any
access-list 122 permit tcp any any range 11000 11999
access-list 122 permit tcp any range 11000 11999 any
access-list 122 permit udp any any eq 2427
access-list 122 permit udp any eq 2427 any
access-list 122 permit tcp any any eq 2748
access-list 122 permit tcp any eq 2748 any
The bandwidths are based on 60 simultaneous G.729 calls
(RTP: 60 channels x 24 kbps = 1440 kbps and Signaling: 60 x 0.5 kbps = 30 kbps).
If you're not using compression then : G.711 - 80kbps x 60 = 4800kbps
Than change the priority value under the policy map from 1400 to 4800kbps.
Keep in mind that you might not need to use all access-groups.These access lists are for signaling protocols such as Skinny, MGCP, H.323.
Also, if you have less b/w on your links than DS0 voice channels, than make sure that you implement, CAC (call admission control) to limit # of voice calls over your T1s, so they wont saturate the link and that will degrade the quality of your voice calls.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
