5Etek-mike,
Thanks you very much for clearing that up. You confirmed what I already thought, I've been confused a lot by my telco. I'll make sure to find another tech for confirmation.
(Moving on)
Here are some of my notes. Feel free to double check and add suggestions:
MIGRATION:
STEP 1)
Contact Telco and move over one of the 'last mile' smart jacks from Mitel to Asterisk PRI.
-Configured Asterisk interface
span=1,1,0,esf,b8zs
span=2,1,0,esf,b8zs
bchan=1-23
dchan=24
bchan=25-47
dchan=48
switchtype=national
-Coordinate/Troubleshoot connection with Telco.
-Work out Red Alarms
-Telco supports Yellow Alarms
STEP 2) Make a T-1 Crossover Cable
1  4
2  5
4  1
5  2
(Someone verify the pin-outs for me)
STEP 3)
Enable E&M Emulation on one of my Mitel PBX trunks/T1.
-Connect Crossover to Asterisk.
-Make sure Asterisk is passing proper Coding and Framing.
-Do I need to providing time? Or is that only with PRI?
Clock mode = Master
span=3,1,0,sf,b8zs
span=4,1,0,sf,ami
switchtype=qsig (Might not be needed)
-Troubleshoot line as needed with Asterisk/Sangoma IRC channel and you guys. :-)
STEP 4)
As lines work Repeat 1-3 for another trunk.
-Two PRI interfaces from Telco to Asterisk.
-Two Mitel Crossover connections.
-Checking all the while for excessive busy signals.
STEP 5)
Setup a Basic forwarding dial plan(s)
-Asterisk forwards incoming PSTN calls to Mitel PBX. For every DID we have.
-Asterisk forwards all outgoing PSTN calls to Telco. For every DID we have.
-Add, strip, or forward 9-to-dial-out
-Troubleshoot Mitel/Asterisk forwarding as necessary.
(Note: All phones still on Mitel)
STEP 6)
VoIP Dail Plan.
-Extension 1234: Converts to VoIP.
-Redirect Asterisk incoming DID PSTN requests for that number to network phone.
-Redirect Mitel calls of 1234 to forward to pseudo 9-4321 (Which is directed outbound to Asterisk. I’ve done this for Cellphone forwarding before.)
-Asterisk picks up 4321 calls (received from Mitel) and directs it to Network Phone.
-Asterisk already programmed to forward 1234’s calls to Mitel via last script
-Asterisk already passes 1234 outbound if 9 is added.
-Notify users that they will receive new Voice Mail box.
More Questions Regarding this Migration:
-Do I need to provide timing to the Mitel?
-How do I setup E&M emulation? (Form 15 doesn’t appear to be the right screen.)
-Do I really need to setup E&M emulation if I’m just going to pretend to be the PSTN (as far as my Mitel is concerned).
