I have an MGCP gateway that has an issue connecting to a couple of fax numbers. I know the numbers work, but for whatever reason the call never stays connected. Does anyone have any ideas how I can go about troubleshooting this issue?
Try upgrading to 12.4(15)T8. Unless you're using T38, then stay far away.
If you're using T38, try 12.4(22)T.
