No Redundancy for Inbound Calls

Dear all,

We have 2 CallManagers at our organization. Incoming calls are routed to Attendant Console to listening Music on Hold. Whenever the Publisher CallManager is down, calls coming into our organization receive a busy signal. I thought we were setup for redundancy, but I found out the hard way that this was not the case.


We have a 2911 router which routes incoming phone traffic into our organization. On it are two dial peers which route our organization?s incoming calls to the CallManagers. The primary dial peer is supposed to route to the publishe  and the secondary dial peer to the subscriber. Below are the 2 dial peers which route our traffic.

voice class h323 1
  h225 timeout tcp establish 3

dial-peer voice 11 voip
 preference 2
 destination-pattern 3.......
 session target ipv4:10.1.11.30 ( publiser)
 dtmf-relay h245-alphanumeric
 codec g711alaw
!
dial-peer voice 10 voip
 preference 1
 destination-pattern 3.......
 session target ipv4:10.1.11.31 ( subcriber)
 dtmf-relay h245-alphanumeric
 codec g711alaw

If i delete dial peer voice 11, incoming call can route to subcriber successfully
 I would appreciate anyone taking the time to look at them and offer any suggestions.

CCM 10.0

I got debug for this as below:

TSI-DC-VGR01-0#end
Translating "end"

% Bad IP address or host name
Translating "end"

% Unknown command or computer name, or unable to find computer address

Hi No, it is not for change

Hi

 

No, it is not for change codec , you can take a look i use g711 & g729 under voice-class codec ,but i share with him a success configuration for me to see if he can see h323 command , may be there is a bug or he has to upgrade the IOS , it is very strange that he is unable to see h323 under dial-peer. I agree with you 100% that he has to apply voice-class h323 1. I need to see may be my configuration can solve the issue.

 

thanks

This is most likely because

This is most likely because you didnt apply your voice class h323 to the dial-peers..

dial-peer voice 11 voip

voice-class h323 1

dial-peer voice 10 voip

voice-class h323 1

 

This command basically tells the router to fail over to the next dial-peer in 3sec. without this, the default failover time for cisco dial-peers is 12sec. The problem with this is that the isdn timeout timer is 10sec, so before the call fails over to the second dial-peer, your provider would have terminated the call. So you need to apply this tom ake the fail over happen well below the 10sec time

What is the IOS version on

What is the IOS version on your gateway. I have never seen a case where the voice class command doesnt show in your dial-peer. That doesnt look right.

Islam,Why are we asking him

Islam,

Why are we asking him to change the voice class codec? Is this related to the problem at hand?

Dear Okanlawon & islam.kamal

Dear Okanlawon & islam.kamal,

Both of you are correct. I used your command and it worked now. It also help me solved the problem related to Music On Hold cause i use g711ulaw ( MoH wont work with incoming call).

I used c2900-universalk9-mz.SPA.151-4.M4.bin
