Hello everyone,
first I want to let you all know that while this is my first post here I have derived much help from this board over the years. Now onto the issue, I've recently been hired by a local Hospital that has a rather complex phone system, the primary system is a Mitel SX200 lite, this system is tied to another SX200 lite via a point to point T1. For many years this was the whole system, however, the powers that be decided to switch to a Shoretel IP system and as it’s a hospital, a straight cutover is out of the question as services MUST remain up. Onward with the complication :bang: ... so the Shoretel is partially installed. so this is how it is now. the primary SX200 is tied via T1 to the secondary SX200(in another building in the campus) the primary SX200 is also tied via a point to point T1 to an SX200 ICP which is then tied to the Shoretel system with another point to point T1. This all works now. The issue is that as they installed new Shoretel phones they just added ARS entries to allow Mitel users to dial Shoretel extensions but now the ARS table is full and the install has ground to a halt. This is the state of these systems now. So my question is, is there a way to either expand the ARS table or go around it entirely using station vacant number routing or station illegal number routing (in the call rerouting table) to send "illegal extensions"(extensions that have been migrated to the Shoretel) from the Mitel to the Shoretel with the correct dial string to call the appropriate ext. on the Shoretel. Sorry for the wall of text, let me know what you think and thank you in advance!

Also, is there a way to pass the DIALED number thru a forward? this may be impossible in the SX200 lite but....

Um... Okay, I'm baffled. Let's map this. So you've got...

200-Light=======200-Light

And they changed that to

200-Light=======200-Light=====200-ICP=====ShoreTel

Is that the picture?

And the problem is a Mitel user at the far left 200-Light trying to dial the shoretel at the far end?

Yes, yes, there is a way to clean that up. What you need to do is to clean up your dialing plan. It sounds like right now your ARS tables are full of extension numbers, which is just wrong.

First, assign each location a range of station numbers:

A = 1000 - 1799 (the first SX-200 Light)
B = 2000 - 2199 (the second SX-200 Light)
C = 3000 - 3299 (the ICP)
D = 4000 - 4299 (the shoretel)

In form 26 of the FIRST sx-200 Light, make 2, 3, and 4 leading digits which point to the T-1 to the second 200-light.

In the second 200-light, make 1 a leading digit that points to the first 200-light, and 3 and 4 leading digits that point to the ICP.

In the ICP, make 1 and 2 leading digits to the second 200-light, and 4 a leading digit that points to the shoretel.

For the shoretel, you're on your own with ARS. BTHOM.

You will also want a leading digit for dialing out (usually 9) and if you want to call out from other switches, you may want leading digits to do that, also (usually 8, 72, 73, 74, etc.).

In 26* for the 1, 2, 3, and 4 entries, you only need minimal direction: leading 1, then 0 with 2 digits to follow covers 1000 - 1099, etc. and they all point to a route that uses the point-to-point T-1 with no digit modifications.

Obviously, on the dialing-out routes, you want to strip access codes and you need a fuller table in 26* for those access codes (9, 8, 72, etc.).

But careful construction of the outdialing routes should leave plenty of room in the tables.

Remember that with mitel, you don't have to completely spell out every possible digit dialed. And Mitel does permit conflict dialing.

Not sure what you mean by this. So I dial 555-0123 and it goes to extension 1123, which is CFA to the second 200-light, but you want the second 200-light to get the dialed digits 555-0123?

Something like that?

So, is the end game to cut over the entire complex to the Shoretel?

If all you are doing is making routes through the Mitels to the Shoretel, then everything Telephoneguy wrote is accurate.

If you want to pass on dialed numbers, then things get a little fuzzy. Are the outgoing trunks in the Mitel or the Shoretel? If the trunking is located in the Shoretel, then choose the leading digit for the Shoretel and in the dialed digits input xxxxxxxx for as many digits to follow as you need. The Mitel will only look at the first digit and pass on everything else.
