Fax Problem

Unanswered Question
Aug 23rd, 2007


We have a fax machine connected to an FXS port. Many times the fax machine port does not go down (Hang Up) after receiving or sending a fax. Therefore, users when they try to use the fax machine they don't a dial tone on the fax machine.

If we leave it for sometime like 15 minutes the port seems to hangup and users are able to use the fax machine again.

THis is an intermittent problem where sometimes the fax machine runs for a week without any problem.

Any ideas are highly appreicated,


I have this problem too.

Anybody thinks it is an IOS Issue? I have found that the client is runnig a deffered release.

I hope the upgrade would solve the problem.

My client is having a similar issue. The vg224 that my client has has the following IOS version:

vg224-16S-M version 12.3(4)XD

My question is, can i simply upgrade to the latest, like something in the 12.4 IOS??? Is there any issues from upgrading from 12.3 to 12.4??

Any suggestions?

I have upgraded the IOS on the router to a stable version. After the upgrade the problem disappeared.

Therefore, try to upgrade the VG IOS and check if this resolves the issue.

Hope this helps,
