Hi folks I wonder if any of you phone techies could help me with this simple job.

Basically I want to put a cordless handset on one of my extensions for my warehouse manager so he can carry his extension around with him.

I have 2 analogue sockets which at the moment are used for incoming and outgoing fax machines. So he could share the outgoing fax extension.

I have figured out that the outgoing fax machine is on extension 223 and i can contact other extensions from the fax machine

But whoever installed the system has blocked dialling the extension number 223. (probably to prevent ppl dialling the fax machine and confusing it)

However I want to lift the block on dialing extension 223 and I dont really know where to start.

Thanks for reading, all help appreciated.

Regards

Russ
