Network Out of order

Hi all,

I have two VG routers- router 1 and router 2-  both have the same configuration and were working fine, suddenly one of them can place calls to PSTN but no in-bound calls from PSTN. to be more accurate the routers have Auto-Attendant script, if I called the router1 I can here the AA message and once I entered the extension, the router reply the destination un-reachable. router2 is OK.

I tried to use csim start XXXX from router 2 is Ok and the phone is ringing. but from router 1 no.

I used debug voice ccapi inout I found disconnect cause 38 which is network out of order. any body can tell me what is the meaning of that and if any body can tell how to solve this it will be very appreciated

I attached the debug. I placed calls to extension using csim start and I called from my mobile and press 0 to reach the operator but no luck.

Re: Network Out of order

Hi

The Gateway is doing what it should do.

Make sure Callmanager has 172.20.170.2 as H323 GW.

I saw a incoming call to the gw from 172.20.104.6. I hope 172.20.170.2 is configured properly. If that is the case, I can only think that CSS on the GW config on CUCM causing it to match some other device.

Call manager trace would have been very good. But if you have problem collecting it, can you give the snapshot of the GW config on the callmanager?

Thank you

Re: Network Out of order

Anybody can tell me what is the meaning of the word Network?

Shall I check network connectivity or Networking issues.

Or the network here maybe IPT network?

Re: Network Out of order

Hi,

Can you attach a show run?

What are the phones registered to, call manager?  What is the call flow look like, do you have PRI's coming in from the pstn and are using H323 to the CUCM?

thanks,

Re: Network Out of order

Thank you for your reply

I am using CallManager 7

I have FXO cards>> its-CISCO.2.0.1.0.tcl application >> CUCM

No Pri connected

Re: Network Out of order

Hi

Network Out of Order means that the gateway not able to establish tcp connection to the peer, or peer is unreachable.

Now, Call manager wouldn't response if the h225 request coming from known address.

I see you have h323-gateway voip bind command under GigabitEthernet0/0. So I am assuming that you've added 172.20.170.2 to cucm.

now what about "ip access-group ASD-Sulay out" ? I didn't see any access-list configured. Did you try removing it?

You can try debuging "debug ip tcp transaction" and "debug ip tcp port 1720"

Thank you

Re: Network Out of order

Looks like TCP session establishes properly for 1720.
Can you collect "debug h225 asn1" from the gateway and cucm trace from the  72.20.104.6( make sure it is set to detail)

Thank you

Re: Network Out of order

Thank you too much Abu hadee,

I collect the output of debug h225 asn1

and I will try to collect the traces ASAP.

Hope we can solve the problem with out the traces.

Re: Network Out of order

YOU ARE THE MAN.

Thank you too much for your support.

somebody changed the IP address of the gateway and this was the problem.

I cahnged the Device name and reset the gateway and it is OK now.

Thank you toooo much.

I just need to ask you one more thing, where I can find more details about the debug commands. like in my case I traced the output I found disconnect cause 38 which is Network out of order. but I did not find any thing to give me more details about the meaning and causes for this error.

when you asked me to collect the h225 asn1 I did not understand anything from the output.

So, any reference for this?

I realy appreciate your support and again thank you too much.
