Incoming call not working

[bahman.tajkarimi]

Hello Guys,

I have an issue with the incoming calls. We I dial the 10 digitss number using my Cell phone, it doesn't go through. I receive a message stating "the call can't go through". But we can call from inside to outside and within the company.

Also when I try to add a dial-peer, an error message stating "Could not add peer" appears.

Could you please help me out?

The gateway is a 3640 H.323.

This is the output of the debug isdn q931. I am dialing 617-717-7982.

From your output it would seem that your striping digits off.

If your dialing 617-717-7982, but the ISDN is presented with only the last 4 digits, "Called Party Number i = 0xA1, '7982'"

Can you provide the configuration?

[bahman.tajkarimi]

Thanks for your help,

Attached is the config

Thanks again,

Sorry, I miss read the initial problem, I thought that you where having problems without bound calls.

I can see from the configuration that there are two matching dial-peers, 7100 and 7200.

I've noticed that the interface F0/0 is missing the command 'h323-gateway voip interface'

The error is in the debug is 'Disconnect Cause=38' this is typically casued by connection issues.

The gateway is not able to make a TCP connection to the CallManager. In the debugs see the gateway trying dial peer 7100 then dial peer 7200. This indicates to me the GW is not able to make a TCP connection to the CCM.

How has the gateway been setup in CallManager, DNS name or IP Address, make sure that Callmanager can resolve the gateway and ping etc.

Thanks for the reply,

Please note that we're able to make outbound calls for any number. 4 digits dialing working fine as well.

May be the h323-gatway command was missing in the config that I posted but I do have that command under the F0/0 Interface. Here's the config for the F0/0 Interface:

interface FastEthernet0/0

ip address 172.16.XXX.1 255.255.255.0

ip route-cache flow

speed 100

full-duplex

h323-gateway voip bind srcaddr 172.16.XXX.1

I See the GW is registered with CCM. As I said the only issue is that I can't receive any calls comming from PSTN network.

Thanks,

[leemj001]

I've always used the addtional command "h323-gateway voip interface"

But as you say you can make outbound calls.

Have you tried using the hidden command 'csim start ' to see if the gateway can make the call?

Sorry I can't be anymore help.

I am in desprate need of help for this issue, can someone please help?

sounds like possibly a naming / IP address reference issue with the CallManager and H.323 GW. (I am assuming this is CCM from your session target...) I would try deleting the H.323 entry for this gateway and re-adding it, or, better yet, just Stop and Start CCM service, if you can.....

Thanks for the reply,

My question is why are we able to make outbound call if the session-targat address is wrong. Please consider the following two Dial-peer. For a call coming in from PSTN, which Dial-peer is going to be used? Accroding to me the Dial-peer voice 1001 will be used because the call is coming from PSTN therefore it going to use the PRI. Am I right?

dial-peer voice 7000 voip

preference 1

destination-pattern 7577

session target ipv4:172.16.165.10

incoming called-number .

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad

dial-peer voice 1001 pots

preference 1

destination-pattern [2-9].........

direct-inward-dial

port 1/0:23

forward-digits all

Could someone please respond to this posting?

Hi,

Outbound calls use the dial-peer pots and incoming calls use the dial-peer voip. Thats why you can make outboud calls even the CCM addres is wrong..
