System says extention invalide but it

Hi,

Sometimes I receive calls from users telling me that when outside people call and once automated service answers, they put a valid extension but the system replies that the extension is invalid.

From inside the network, I can call the extension no problem. I even call with the outside number and able to access extension. Can’t recreate the problem.

It is getting to be a nuisance as I receive often emails from remote sites informing me of this problem. Problem does not happen every day. But on a day it happens, it happens often and with different extensions.

Also we have a few sites, and I only have problems with this perticular site.

Thanks in advance fopr any help provided.

We also had a few customers telling us the same thing and the only time we were able to recreate it is by dialing the extension numbers really quickly.

Were you able to find the cause of this problem?
