This is one of the best switches ever made. With a little care there is no reason change. You stated the great track record it has. If concerned you can buy spares on ebay..
As for adding VOip trunking you can. You need a T1 card and configure it as tie and connect the T1 to a Cisco router. Let the Cisco route from point X to Y. works great. ISDN use an atlas 500, forget the IPDN card. What more do you need.

I CUT MY TEETH ON 7K THEN FOLLOWED THE PRODUCT LINE UP TILL 9005 AND IT WAS THE BEST SWITCH I EVER WORKED ON. TODAY I WORK ON NORTEL , ROLM, AVAYA AND CISCO THERE IS NO SOFTWARE CORRUPTION LIKE NORTEL HAS.

Yes, bringing another old thread to life LOL.

I heard that 2008 will be the "end of life" for the 9751 (9005). I'm not sure exactly how the support will change, but it does give the service vendor room to increase service contracts and wiggle out of 100% guarnteed support.

There's probably still more than enough parts to keep this thing running for another decade, but we are looking to replace the 9751 in 2008 (supposedly).

I'd say the only nagging problem I've ever experienced was the upgrade from 9004 to 9005 and the Expander circus. It's settled down now, but for awhile, I was chasing my tail with different expanders failing all over 16 shelves, ISB errors, etc.

Other than that, the Rolm 9751 has been great. I've also worked on (old) Northern SL1, Mitel, etc.etc...

So it looks like 2008 is the year.

9751 Systems were a solid PBX for the 80's and Siemens cut development around 1995 and ever since there was no software changes, I believe the last know release was 9005.6.83. If you only care about dial tone and no new features, that system should work great!.

There is a small company Telcom System and services, based in Allentown Penn. they have alot of refurbished materials at a good cost, from cards,phones, PBX's etc.

On the 9751, the last release was 9005.6.84. After that, there was going to be no more release. At the time (about 10 years ago) the idea was to migrate and do installs of only the Hicom systems. Siemens wanted to only support the Hicom's in the future. This was after they bought out IBM from the Rolm/IBM merger.

The 9751 (9005) and PhoneMail were the 1st systems I learned working at ROLM/Siemens, and then it progressed to everything else.

We have had our 9751 for 19 years and have no doubt that it would last another 20 years; what a great investment.

We've had our 9751 since '93. It has run flawlessly! Only failures have been caused by outside failures. (power, until we got a generator). I have 2900 lines. Analog and didital. We are in the stages of going VoIP, but will keep the 9751 for our critical applications (emergency phones, etc.).

So Ned, you are going VoIP with a T1 or Tie service to your 9751?

I'm curious why the company didn't change it all out, or is that the 2nd phase?

Is your company in health care?

Like I mentioned before, we are supposedly authorized for funds in 2008 for consultants and PBX replacement/consolidation of remote sites.

I'm sure you've gone through (or are going through) this change, any advice or comments?
Thanks,

Dave

Any they are fast and friendly.. Helped me out of a couple of jamms. Your system should run for another 5 or so years without any major problems like Pedro saisd as long as your not looking to add features.
It was the first system I had as well I went to school for it. I was in the second class they offered covering it.
