Extensions stop working a LOT.. Have to dial complete number..

[rake-support]

Does anyone know what would cause extensions to stop working? this happens daily to at least one of us.. If we dial a co-workers extension, they can pickup.. but not hear anything, or they don't get the call at all.. but if we dial the complete number, they can get the call. This started happening a while back over-night.. and I can't seem to find out what is going on.

Thanks for any Help you can give!

Hi Darrell,

You the more information you post here the higher the chance someone may be able to help.

Good things to include as a starting point would be:

• Exact version of your PBX
• How the phones connect to the PBX
• If any changes have been made recently on your network/hardware/3CX install
• Whether you see very high usage on your management console
• Whether the firewall test passes all checks
