I am currently in the middle of an install putting in a new Mitel 3300 and pulling out at Norstar 0x32. It is about 60 or sets. The customer was wanting to get into IP so that they could put remote sets in different feild offices around the province to reduce LD, etc. They also like the advantage of lower MAC costs in administrating their own phones. The quote went out to the customer with several different options and 2 of them had the customer keeping their existing Nortel sets. The first was an upgrade to a BCM which was the most expensive. The second was a Mitel 3300ICP with the Citelink Gateway using the existing Nortel Sets. This was the cheapest. The last option was about 2 grand more and was the 3300 and all new Mitel IP sets.
The customer chose the last option with all new sets for a couple reasons.
1. When you are spend 40k plus for phones it really helps if the bosses and other end users actually see something new, instead of the old beat up phone they have had on their desk for the past 6 years. The average user doesn't care about the box in the phone room and the fact that it can be programmed through the web, etc. To them it is the same old thing.
2. Using the Citelink on a different PBX would really screw up the end user, since the keys are all remapped. Your set would say Norstar but it is not. I would imagine huge pushback from the average user. Could you imagine if suddenly all the mice in your office were switched for left-handed use?
The biggest reasons for upgrading using the Citelink is that it is an in for a competitor to sell a new phone system while allowing the customer to retain some of their original investment. It makes it "more justifiable" to the guy looking at the price tag.
Upgrading to a BCM. The only advantages that I have seen to date are: IP Sets, remote and local; IP Trunking; Unified messaging; lower MAC costs to the customer, bad for vendor, good for customer;
What ever you decide, make sure that in the end, the people in power see something new on the desk. :-D
