The country codes are not used, if the call is not international.

All sorts of information. Another search for the E.164 standard is revealing also. Lots of standards, so little code space.
Hi Al,
I did something like this three years ago, using a Multi-Tech modem for CDMA networks. (CDMA is popular here in the US, most of Europe is GSM.) I allocated an array with ten bytes, three for the area code, and seven for the mobile telephone number. On our network you don't have to dial a 1 first, but other networks might require it. When a user sent an SMS message in to the system they had to have a command and a four digit password in the body of the message. Then the system sent back a response to the phone number that came in on their message, in the caller id header.
If the command wasn't valid, or the password wasn't valid then it sent back a message to that effect.
If you'd like to see it I can post the code, but it will take me a day or so to find it, it's on a back up disk somewhere.
Jerry.
