PSTN calls

Unanswered Question
Oct 5th, 2009

Hi All,

We are facing a problem while making PSTN calls to outside world using Cisco 2800 router configured as H.323 Gateway & integrated to Call Manager version 4.x.

On the router we have , VWIC-2MFT-E1 card on which PRI is terminated.

Setup was working fine but now when we call up, we need to dial two or 3 times before call gets matured.

router detail : c2800nm-spservicesk9-mz.123-11.T10.bin

can somebody guide on the same...

regds,

aman

Check status of your e1 line.

Show controller e1 x/x brief and show isdn service.

you can run debug isdn q931 and check what's going on as well.

Can you post the results of

sh isdn status

sh voice dsp

sh voice call summary

Do you know how many B and D channels you have on your PRI, could be possible that your using all the channels available on the PRI.

Regards,

Justin
