Can't work out call flows

[billz0r]

So we have a Mitel system that someone else installed but we're stuck supporting it. I'm having trouble working out how the inbound call flow was configured.
So far I have:
1) Call comes in on external DID, I can see that in the Direct Inwards Dialing Service table. The DID is told to go to ext 899.
2) I look in the Call Rerouting table and find Number 899. It's told to go to Call Rerouting  - Day (1) and Call - Rerouting - Night1/2 (2).
3) I then look in the Call Rerouting Always Alternative table (this is the correct place right?). ID 1 has No Reroute on all columns and ID 2 reroutes to directory number 770. 770 is the NuPoint extension which will be for Night Service voicemail.
My query is since ID 1 has no No Reroute, how do I find out where the call goes then?
On the phones they have 2 buttons for Line 1 and Line 2 Key System (ext 901 and 902) and they're the phones that ring when a call comes in.
I don't know how the calls goes from ext 899 and no Reroute to ext 901 or 902.
There are no hunt or ring groups containing 901 or 902 either.
I'm missing a menu somewhere.

Thanks in advance.

I would start with LOCATE NUMBER 899 in Maintenance Commands. Post the results of that and it will give us an idea of where to start.

Thank you so much. 899 is a hunt group (was on page 2 and didn't notice 2 pages.)
Members of that hunt group were 901 and 901.

Loc Num is on of the first commands I use during call routing troubleshooting. Only way to start this IMHO

Thanks for the tip. I used Test Extension in this case and that gave me the info I needed but I'll keep that command in mind for as well.

I've been doing Mitel since the 90's but there is always something new I see that that may make me try a different approach
