How to fix an occassional fast-busy?

Unanswered Question
Nov 13th, 2008

I have this problem wherein I'm getting an occassional fast-busy when dialing from GW to another GW. The Disconnect Code I'm getting is "38" from CCAPI debug as shown below. This usually occurs when a I call a different number immediately (about 5 - 10 secs) after releasing the first.

I have tried switching from H323 "faststart" to "slowstart" but with the same result. I can also ping the other GW so it can't be unreachable.

Can you lead me on where to focus to fix the issue?

ever try to use: 'progress_ind' in dial-peer for the related calls?

I have similar issue -

Whenever phone placeed call and got fast busy tone (ie, no bandwidth or no valid desti number), the ephone will get fast busy tone always.

I think this is due to the cisco phone image is not compatible with VGW (CME)- since I use the upgraded phone with load: p00308000800 but my CME router has lower ver load.

Can you confirm if your phone load is same as your CME/SRST router?
