However, nearly all manufacturers appear to lure users into a cul-de-sac in respect of upgrades these days. Sure, you can have SIP trunks, etc, etc, but at the loss of flexibility in any of the slots. <i>You'd like to swap a digital card for an analogue, sir? Certainly! Could I have your purchase order for the new license, please?"</i> We've already picked up a few large chunks of business through OEMs trying to implement an upgrade leading to total loss of flexibility,and we have installed a PABX of at least five years vintage, which has offered a pool of trunks and extensions which the customer can configure to their heart's content. Oh, and we networked one of the customer's sites via VOIP, using an existing WAN, the best of both worlds indeed, but that's another story... Wise words.

The Siemens ISDX & Realitis at a revision 9 software will support IP desktop and IP Trunking. Many customers are making savings on 2meg DPNSS leased circiuts and utilising IP Trunking instead. Easily done and very successful in my experience. Software 9.2 offers SIP trunking for conectivity to the Hipath 8000 etc. For me Voip can be implemented sensibly, some customers moving totally to voip are finding speech issues & less features. Speak to your PABX supplier/engineer as you maybe surprised at what your current system can offer. I setup a pickup group for a customer the other day she was amazed and had been up and down answering calls at other peoples desks for years. Long live TDM....!

We are removing perfectly servicable equipment which has served organisations for over twenty years. Much of it was built to military/government specifications, in the days of The Cold War and The GPO. It chugs away, requiring very little mainentance. Will the latest server-based equipment still be around in 2021, based as it is on hardware that traces its ancestry back to IBM desktop You betcha stam and clockwork lasts: we run a pair of strowger pabx3 (1965 & 1974) linked together which provide a total coverage of our preserved railway line. we recently had a VOIP specialist company in to give us a "free" assesment of how VOIP could help our business, when i told him some of our extensions were 6 miles long, he quickly coughed and left. I didn't have the heart to tell him, that we also used DACS on some of the long line extensions! :-) Steam and Clockwork Lasts.

In Germany they run ADSL over ISDN so why can't we? There is also a healthy market there for ISDN media adapters, which allow ISDN systems (or cards) to talk to VoIP without trashing all the wiring, replacing the handsets etc. Yet few folk in the UK market such gear. Worth a look though.
