What is disconnect cause code 0

[kumarss77]

Hi,

What is disconnect cause 0. ?

Enabled CDR logging for VoIP, and in many calls i get disconnect cause code '0', with no disconnect text.

Can some one give more details on what could be the actual reason. Cisco wesite says 'this is just a cosmetic change', then what is the cause?

According to the following link, cause code 0 is No Error. The link in your post above indicates that seeing a lot of these is simply a defect in your version of IOS that has no real impact.

This is the debug isdn q931, and cdr output together.

I have noticed that the reverse call leg generates Disconnect cause code 0, WHEN I WITHDRAW THE DIAL IMMEDIATELY, before getting any response from the other side.
