For mobile origination, a gateway profile provides two key pieces of information: how to identify SMS messages intended for that profile and how to convert those messages to email messages. Note that this profile can be the same one used for email-to-mobile with the addition of the SELECT_RE option.
To configure the gateway profile, follow these steps:
Add a gateway profile (option group) to the SMS Gateway Server’s configuration file.
To add an option group, use the following format:
[GATEWAY_PROFILE=profile_name] option-name-1=option-value-1 option-name-2=option-value-2 ... option-name-n=option-value-n
Any name of 11 characters or less may be used for the profile’s name. All that matters is that it is not already used for another gateway profile within the same configuration file.
Set the SELECT_RE option must be specified for each gateway profile.
The value of this option is an ASCII regular expression with which to compare SMS destination addresses. If an SMS destination address matches the regular expression, then the SMS message is sent through the gateway to email using the characteristics described by the matching profile.
It is important to note that it is possible to configure multiple gateway profiles which have overlapping sets of SMS addresses (for example, a profile which matches the address 000 and another which matches any other three-digit address). However, so doing should be avoided as an SMS message will be passed off to only one gateway profile: the first one which matches. And, moreover, the order in which they are compared is undefined.
Set the CHANNEL option.
Its value should be the name of the MTA’s SMS channel.
