Apparently the SL-1 I can't help you with an SL-1's programming, but I will tell you what I do with a Mitel SX-200, and it may help. Before you pick the trunk group to use, you must look at more digits! Consider: 011+ is for direct dialed with NO operator assistance 01+ is for direct dialed WITH operator assistance (the next digit must obviously test NOT a 1) 00 is just to reach the IXC operator In your environment, you want to route the first onto your regular trunks for pricing by your own call accounting machine, but the last two MUST go to HOBIC trunks. For customer sanity, and to keep existing instructions on phones valid, it is often simplest to simply treat 8+ and 9+ identically, and YOU do the route selection based on what else is dialed. The smart exception to 8+ = 9+ is to treat 9+11 as a panicked 9+911, and allow both those and 8+911 from ANY phone reguardless of how otherwise restricted. That includes maid's closets, elevator, lobby house phones, pool area phones and phones that can't even terminate an incoming call. The other reasonable option is to totally DUMP hobic! and get 'screening 94' or whatever they call it where you are. This says allow 0+ on the trunk, but NOTHING gets billed back to the property. Obviously CC, 3rd party, collect, and free calls are about all that get through. You can have this on a regular trunk where 1+ (that your accounting box can price) can go anywhere. The HOBIC folks won't allow you to keep HOBIC if you are also using screening. All you have lost is 'bill-to-the-room' operator handled services. Your call accounting probably posts to the room's bill automatically, HOBIC may, but often is a manual posting pain - worth losing. At 200 rooms, why don't you have T1 into some IXC's POP for some serious low cost service? The following is a more general comment on carrier access from hotels, hospitals, prisons, school dorms, nursing homes, timeshare condos, etc. For fairness to all CC users, it would be 'nice' to allow 10xxx0+ routing, but a hotel clearly wants to prohibit 10xxx1+ because they are reselling those calls and MUST control what carrier is used. What would solve lots of problems would be for the LEC to offer a class of screening where 10xxx routing would only work for 0+ calls and they would also be subject to the 'bill elsewhere' restrictions currently provided by 'screening 94' or whatever it is. Any call would be valid as 1+ traffic to the default carrier on the same trunks. This does eliminate requests for AT&T to provide feature group B (950 type) access for their card users in non-AT&T hotels, and also helps stamp out feature group B trunks in general. If you like the idea, tell 1) your LEC, 2) your DPU, 3) your Senators, and 4) your IXCs.
