When I have to call our IT department I dial 111 from my extension and when they have to contact me they have to press 222. We are lucky to have such nelson figures as our extension numbers. Easy to remember, recollect, dial and speak. The next time when the EPABX guy comes to your office for rebuilding the telephone systems and infrastructure, whisper into his ears. INTERESTING NUMBERS PLEASE!!! If he is not ready to do this special favor, bribe him. If he is a smoker give him a pack of UDAN GARAM and if he is a drinker a kingfisher beer will work.
