Re: Incoming call using H-323

Is 10.2.100.15 pingable from router? Is router address configured as GW in it ?

New Member

Re: Incoming call using H-323

yes I can ping 10.2.100.15 (publisher) abd 10.2.100.16 (subscriber)

i didn't understand the second question

Re: Incoming call using H-323

In the CM you need to configure an h.323 GW with the corresponding address. Then you can look at debug ccapi to see why CM is refusing the call.

Re: Incoming call using H-323

I have the GW configured in CCM.

and I have the ccapi debug turned on, however on incoming calls the only thing I see is

*May 26 21:51:43.531: ISDN Se0/0/0:23 Q931: RX <- SETUP pd = 8 callref = 0x016A

however for outgoing calls i see the complete output from the ccapi debug

Re: Incoming call using H-323

You can try debug cch323 but I'm afraid you will only see thta CM is not responding. Perhaps you need to restart something there.

Unfortunately I'm not an expert at CM, hope somebody else can help.

Re: Incoming call using H-323

I see that the incoming number that telco is sending you is 7070. In the call manager, what do you have programmed as 7070? Do a route plan report in the CCM on DN 7070 and see what comes up. Is it a phone, a CTI Route Point, a translation pattern? If it is a phone, see if that phone that has the DN 7070 on it is registered. If the call hits a translation pattern in the CCM, see that the translation pattern is correctly configured in the CCM. Are you getting ringback when the number is dialed? If not, what message are you getting?

Re: Incoming call using H-323

7070 is a translation pattern that will translate into 6001, 6001 is a shared line

I have the 2 protocols running on the GW; MGCP and H323, I turn off MGCP with the command "no mgcp" and then I try the call and nothing happens, however if I issue "mgcp" the call goes through

I listen to dead air and then fast busy

Re: Incoming call using H-323

How is the gateway (PRI) configured in the CCM? Is it MGCP or H.323? If it is an MGCP gateway, under the MGCP PRI configuration, there is an place where you can enter the attendant DN. In the Attendant DN field, enter 7070. Therefore when the call hits the call manager, it will see the call being presented as 7070, which in turn will hit the translation pattern and send the call to the phones that are registered with DN 6001.

Hope that helped

Re: Incoming call using H-323

If it works as MGCP but not H323, do you have h323-bind configured on the relevant interface?

New Member

Re: Incoming call using H-323

yes

interface Gi0/0

description voice

h323-gateway voip interface

h323-gateway voip bind srcaddr 10.3.100.1

We want to get rid of MGCP due to a few delay issues that we are facing. But I just cannot get the incoming calls to work properly
