Solved: h323 gateway redundant call manager - Page 2

dan.letkeman · ‎12-27-2012

Hello,

I am trying to setup a redunant connection from a 2921 voice router to both my publisher and my subscriber call manager. Everything is working when the publisher is running, but I recently did an upgrade and when the publisher (10.1.1.11) was down, the outside callers could not call in, they just got a busy signal. All of our phones automatically registered with the subscriber so that part worked fine, but no outside calls made it through the router.

Dial-peer 503, and 504 should be failing over.

Here is the relevant config:

Chris,

Not sure how it could be a routing issue when it is working when the publisher is up, but it doesn't work when the publisher is down and only the subscriber is up.

It works fine using the loopback as an h323 interface.

phooghen · ‎12-27-2012

If the H.323 GW is the Pub/SuB default GW (10.1.1.10), IP routing should work.

But it would have been more logical to bind H323 to the Gig 0/0 interface like

interface GigabitEthernet0/0

ip address 10.1.1.10 255.255.255.0

h323-gateway voip interface

h323-gateway voip bind srcaddr 10.1.1.10

duplex auto

speed auto

dan.letkeman · ‎12-27-2012

Yes I had it bound to the G0/0 interface in the past, but I have a few sub interfaces on the router (not in the config I posted) and you cannot have h323 bound to the physical interface and have sub interfaces at the same time.

Dan.

Chris Deren · ‎12-27-2012

Binding to loopback is perfectly fine to accomplish interface redundancy as long as your IP routing is configured properly. Your ping replies did not look too good, which interface did you source it from? Do you have IP routing enabled on the router?

Did you check CUCM logs to see if the call made it there?

Chris

Chris Deren · ‎12-27-2012

You may also want to add the loopback address to the trusted list.

Chris

dan.letkeman · ‎12-27-2012

Yes ip routing is enabled and I am using eigrp.

I agree the pings don't look good. I will look into that as well.

The trusted list is for inbound voip calls, you should not have to add local IP's too it.

http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a0080b3e123.shtml

Still don't think its a routing issue. Its all working fine now that the publisher is up. Seems to me like a configuration issue. I will have to check the logs later.

dan.letkeman · ‎12-27-2012

I believe these ping responses are due to an icmp rate limit. This is by design. I get the same response from other devices to both of the CUCM servers and the Unity server. So routing at this point is not the problem.

Jorge Armijo · ‎12-27-2012

Hi,

In this case the best is to run debugs when attempting calls to the failling server. You can run:

deb isdn q931

deb voice ccapi inout

deb h225 asn1

deb h245 asn1

deb ip tcp trans

We will see if the H323 signaling is taking place and why the call will not work. In addtition, we will see the TCP interaction before the H323 signaling, we will confirm if it's a network problem or not!

Please share with us the logs and we can take a look

Here are the logs from the router with all of the debug commands that you recommended. This is an incoming call from 5553620788 to 3259009. I get a busy signal.

Hi,

I'm looking at the debugs, what is the configuration for dial-peer 501? Can you please send me the complete show run from the Gateway?

This is not much different than the one I posted above. This is everything minus username's and passwords.

It's really very simple, there are two dial-peer's 501,502 that point all of the incoming calls for 5553...... to the two call manager servers. I am thinking that this might be a call manager config issue instead.

Hi,

From the debugs:

-First the call tries to connect to 10.1.1.11; TCP transactions show that the TCP cannot be established:

Dec 28 15:22:42.874: TCP: Random local port generated 41942, network 1

Dec 28 15:22:42.874: TCB2CEF6C08 bound to 10.1.100.100.41942

Dec 28 15:22:42.874: TCP0: state was CLOSED -> SYNSENT [41942 -> 10.1.1.11(1720)]

Dec 28 15:22:42.874: ISDN Se0/0/0:23 Q931: TX -> CALL_PROC pd = 8 callref = 0xFE0C

Dec 28 15:22:44.874: TCP: (41942) -> 10.1.1.11(1720)

Cause Value 38 = CC_CAUSE_NETWORK_OUT_OF_ORDER

-Then the call tries to connect to 10.1.1.12; There is H323 signaling but CUCM sends a release complete:

--snip--

Dec 28 15:22:45.878: H225.0 OUTGOING PDU ::=

value H323_UserInformation ::=

{

h323-uu-pdu

{

h323-message-body releaseComplete :

--snip--

Cause Value 27 = CC_CAUSE_DESTINATION_OUT_OF_ORDER

-As summary, when matching dial-peer 501 TCP link cannot be established. And when matching dial-peer 502 the CUCM rejects the call

-It would be necessary to check the network or the services on the first CUCM and for the second, well to capture CUCM traces to see why CUCM is rejecting the call

Found out after some troubleshooting that is was our Unity server that was missing a server entry in the port group for our subscriber server. This is what was rejecting the call when the publisher was down, because the call was wanting to go to an auto attendant but there was no connection from the subscriber to the unity server.

So for anyone reading this, its not an issue using a loopback interface for an h323 gateway, continuous pings from any device to a cucm server is rate limited by design and will look odd ( !!!!!.!!!!!.!!!!!.!!!!!.!!!!! ), and make sure you have all of your call managers added to the servers list in the port group on your unity servers when you have calls going to auto attendent.

Dan.

Ayodeji Okanlawon · ‎12-29-2012

Dan,

Thanks for updating us on this. However this thread goes a long way to show why it is important to accurately describe the issues you are experiencing. You never mentioned that the an auto-attendant or unity was involved in the call flow. It is important to accurately describe your call flow, the components involved and the problems you are having.

Good luck in the future and see you soon on the forum.
