Hi,
The SL1 was an old Northern Telecom PBX, from the late 1970s/early 1980s - the precursor to the Meridian. I've never seen it refered to as a protocol. Now, if you really means the Meridian Link CTI protocol, then yep, I know about that. They charged a fortune ($25,000 I think) for a copy of the manual last time I asked. I have implemented software to drive a Meridian through that interface. It kept changing quite a bit, and earlier machines don't implement it by TCP/IP over ethernet - I can't remember the interface they used before. They seemed a bit vague about what IP issues they might use to hold people to paying all that money. Trade secrets maybe. Anyway, if you can find a copy of the documentation, the protocol is quite simple. None of that nasty ASN.1, like CSTA. It is a bit like Q.931 messages, if I remember rightly (it was a few years ago).
Regards, Steve

I have been investigating more tight integration between * and the Nortel MICS... it appears that it is at least theoretically possible to have * store voicemail and log which stations call where.
Both require a T1 card. The T1 card requires either a clocking module or the 6-port fiber module to provide T1 timing. Naturally a T100P or TE405P is required on the * side.
To log which stations call where you set up the OLI# on the MICS to set the outgoing caller ID to the station # + some prefix. i.e. you're really configuring the MICS to set the outgoing CID to be a number in a DID pool.
However to get * to gracefully handle the MICS voicemail it appears that you can utilize the centralized voicemail feature on the MICS. It is used to allow Norstar systems to share a voicemail system. This is perfect. :-) However it seems that in setting it up the T1 needs to be set up to use the SL1 protocol.
Does anyone have any more information on the SL1 protocol? I don't expect * to support it currently but I'm more interested in investigating what is required. I think that allowing * to play with these systems nicely will go a LONG way in furthering Asterisk's penetration into the small/mid business market.
Aside: Since we moved to the new building (and * is handling all calls and faxes for us) our * system has handled over 11500 calls. That's over 5500 calls a month, incoming, outgoing and faxes. Not a bad start. :-)
