You really do not need to copy the rules. The rules depend on how connected to the outside world (analog, SIP, PRI, etc.) and possibly, to some degree, on what the room phones may have posted on their face-plates. If SIP, which I take it to be from your last post, most will want to see 11 digits or 10 (US based) regardless of even if a local call. So, grab a phone and create a rule that points to your provider (assumes that one is configured in the system) and in the rule just indicate 11 digits in length and dial a number like you would if it were long distance with the 1-XXX-XXX-XXXX. If that does not work, then change the rule to 10 digits and repeat but without the "1". If SIP and in the US, one of these should work provided that you are indeed configured correctly for your provider. If not, then you may need to do a capture and see what the provider response is or get the provider to assist in the trunk config. You then simply need to add rules in anticipation of how the guest would expect to dial. So, if most expect to call a local number using 7 digits, then you will need to create a rule that will prepend the local area code along with the 1 (if 11 digits are required). Basically, you need the format of the number to always match the 11 or 10 digits with the exception of 3 digit dialing such as may be needed for 411 or other similar services. Also, remember that you may need to strip a number in the event that the phones have directions to dial 9,8 or some other number in order to reach an outside line. And finally, remember to set up emergency calling along with the email notification so that should someone have a need for it, the hotel will get the email informing of the call along with the extension that dialed it. You may also have to consider how to handle emergency calling if the instructions indicate to use a 9 or 8 or similar such that you can handle 911, 8911 and 9911 for instance. No matter the scenario, by law in the US, a guest must be able to dial 911 without any preceding numbers but if the phones indicate an additional digit is needed. you have to be prepared to accommodate it such that it will reach 911. For hotels, I always use a Grandstream HT503 with an analog line. I want the local responders to take and manage the call rather than e911. I also use the phone side to connect an analog phone at the front desk so they should almost always have a way of calling should the need arise, even if the PBX is down.
