2921 voice gateway dial-peer

[bo liu]

i use 2921 as voice gateway

and have two dial-peer :

dial-peer voice 8000 voip

destination-pattern 8...

session protocol sipv2

session target ipv4:10.10.10.21:5060

voice-class codec 1 

dtmf-relay cisco-rtp h245-alphanumeric h245-signal rtp-nte sip-kpml sip-notify

no vad

!

dial-peer voice 8001 voip

preference 1

destination-pattern 8...

session protocol sipv2

session target ipv4:10.10.10.210:5060

voice-class codec 1 

dtmf-relay cisco-rtp h245-alphanumeric h245-signal rtp-nte sip-kpml sip-notify

no vad

so if 10.10.10.21 down the dial-peer 8001 should transfer the call to 10.10.10.210

but....now i shunt down the NIC of 10.10.10.21 ,and debug voice ccapi

the router also send the call to dial-peer 8000

why this and how should i config the GW???

What is the setup? What does the gateway connect to? Can you provide your full scenario..Do you hae any config that checks the status of the dial-peer...

Try this

conf t

monitor probe icmp-ping 10.10.10.21

Hi,

You need to enable monitor probe icm-ping:

1. Under your dial-peer look into the  "*monitor probe icmp-ping* X.X.X.X"
command. If destination does not respond it shuts down that dial-peer.. therefore
failover should be instant.

2. Global config - you can adjust your timers - it will try 6 times, with 3
sec timeout by default
sip-ua
retry invite 3
timers trying 2

Leo,

The timers trying is in ms (so i think 2 is way too short...) Ideally it should be something like this

sip-ua

retry invite 2
timers trying 150

hi leo

thanks for you reply

in your reply ,the name monitor probe icmp-ping* X.X.X.X is use ICMP? but if my CVP server is runing ,and the Call Server

component is down,can the dial-peer shutdown ?

i another customer use 2821, i'm not config anything ,but the dial-peer can monitor the CVP up or down....

the command is 2900 router new command ?

i find this situation

i configuare the command "preference 1" in dial-peer ,and the two dial-peer can failover

but if the preference 0 dial-peer down ,and a call send in gateway from PSTN,the router will route the call to preference 0 dial-peer , and just route to preference 1 dial-peer about 20S after...

where can i configuare the timer with the preference??
