VOIP phone connection through VPN/leased Line

ssweehinlew · ‎06-21-2015

I built a vpn tunnel to connect HQ network with branch office. The VOIP phone from branch office is connected to the phone system in HQ. The voice is clear but it will get disconnected occasionally. I did the continuously ping from branch office to JQ phone system. There was just only 1 line of time out when it get disconnected. Anything i can fine tune on the cisco switch? QOS need to be configured?

Configuring QOS on your switches will probably help in prioritizing traffic if there is any congestion on the link.

Maybe VPN solution is not feasible. I am thinking to do it on the interface for 10 MB leased line connection and reserve 1 MB for Voice server. The ip phone is located at remote office. Is below configuration correct?

ip access-list extended VOICE
permit tcp host 192.168.3.3 255.255.255.255 any any

policy-map QOS
class VOICE
priority 1024
set dscp ef
class class-default
fair-queue
set dscp default
policy-map ALL
class SHAPING
shape average 10240
service-policy QOS

class-map match-all VOICE
match access-group name VOICE

interface FastEthernet0/0
bandwidth 10240
max-reserved-bandwidth 1024
service-policy output ALL
