I am Facing Voice delay in Cisco Call manager ,Recently we shifted our New Office ....Still on off my Voice Gateway is Connecting Through Data link Connection ....Mostly I am Face Delay ....Like when ever i am calling any External Number ,the receiver cannot able to hear my Voice ...
Is there is Any Way to solve this is issue and this High Priority ............
The following QoS configuration was put in place and the issue was resolved:
QOS: MQC - apply in THIS order
step 1 (optional) define ACL
step 2 define class-map
call ACL above or match something like rtp, dscp, prec)
step 3 define policy-map
call class-map(s) above and allocated bandwidth & set action
step 4 apply the policy-map on step 3 to interfaces or DLCI
MQC EXAMPLE (logical presentation - be sure to apply in the order listed
!! this first part is the shaper which then calls the QoS service policy
shape average 1425000 << based on 1.5 Meg pipe 95% of uplink speed
priority 1050 << based on leaving 375K of a 1.5 Meg link available.
set dscp ef
!! more details of voice-RTP in the class-map below
bandwidth 75 << based on leaving 375 K of a 1.5 Meg link
set dscp af31
!! more details of voice-control in the class map below
!! end policy-map QoS
!! class-map details below
class-map match-any voice-control
match ip dscp af31
match ip dscp cs3
match access-group 101
!! more details on the access list below - choose type of control
class-map match-any voice-RTP
match ip dscp ef
match ip rtp 16384 16383
match access-group name AutoQos-VOIP-RTP
!! more details on the access list below - deals with the ports 16384
ip access-list extended AutoQos-VoIP-RTP
permit udp any any range 16384 32767
!! details on ACCESS-LIST 101 depends upon type of control we are using.
access-list 101 permit udp any any eq 2427
access-list 101 permit tcp any any eq 2428
access-list 101 permit tcp any any range 1718 1720
access-list 101 permit tcp any any eq 1731
!For Skinny (phones registered to CCM)
access-list 101 permit tcp any any eq 2000
access-list 101 permit tcp any any eq 5060
!! DO NOT FORGET TO APPLY MQC (or QoS if you choose not to shape) TO AN
service-policy output MQC
end MQC EXAMPLE

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...
