Problem to make calls from CUCM to CUCME 48XX extensions

[Thiago Gandara]

Hi voice team,

I am having problems connecting to 48XX extensions, these extensions are on a router with CallManager Express, and have a route pattern in CUCM.

But when I make a call to extension 4801 is busy signal, I did a trace on CUCM and produced this result:

CCM | ConnectionManager - wait_AuDisconnectRequest ERROR: NO ENTRY FOUND IN TABLE

Attached to this full trace, I called extension 8009 (CUCM) to 4801 (cucme).

Thanks.

Thiago

You need to send us a debug voip ccapi inout from the ccme router for us to see whats going on. from CUCM we see a h225 setup error  to this device with  IP=10.19.1.254

Hi, I did debug cme on, but nothing appears, the call does not come until the router, the device 10.19.1.254 is the CME Router.

Thanks.

[Ayodeji Okanlawon]

OK. We need to look at your config in CUCM. Have you configured the ccme gateway as an h323 gateway in CUCM? Or are you using a sip trunk to the CCME? What is the status of the ccme gateway in cucm if you have configured it as h323 gateway

Yes, i configured as H.323 gateway, and the status is Ready.

Attached the print screen.

Can you send a sh run of your ccme gateway.

Hi, follow the sh run.

[Ayodeji Okanlawon]

Thiago,

Everything looks fine on the gateway config. Can you add the following dial-peer

dial-peer voice 10 voip

incoming called-number .

no vad

dtmf-relay h245-alpha

NB: This is not going to fix the issue but this is best practice. This dial-peer will bring inbound call from cucm rather than using the default dia-peer 0.

Can you please reset the gateway and do a test call again..

enable "debug voip ccapi inout". If you are telneting into the router you need to enable "term mon".

OK, i put the dial-peer 10 on the Router, and i waiting to proceed with reset, the client was able to tell me when to restart the router.

Thanks.

[Thiago Gandara]

Hi, i reset the router, but the call not complete, busy signal. I enable the debug command but nothing appears.

[Ayodeji Okanlawon]

Ok. So cucm is unable to talk to the gateway using h225 signalling. Can you make call from CME to CUCM? Please do a test call from cme to cucm and send me the ff debug

debug voip ccapi inout

debug ip tcp transaction

debug h225 asn1

I cant make call from CME to CUCM, busy signal to.

[Ayodeji Okanlawon]

Where are the debugs? Please send the debugs for the calls from ccme to cucm.

Hi, I managed to solve the problem. I discovered that the link had a bandwidth optimizer, and was preventing the connections between CUCM and CME.

Thank you for the support
