Hi Tim,
The built in action triggers currently don’t allow you add a number to a group without semicolons. It would need to be done through a custom software using API commands to communicate with the iSMS.
Through the Receive API, the software could receive the “Add groupname” sms message. That software could then issue a sendmsg command to add that sender to the group indicated.
An example of a HTTP sendmesg to add a number to a group would be:
http://192.168.2.1:81/sendmsg?user=user1&passwd=user1&cat=3&enc=0&text=ADDG;groupname;sendername;sendernumber
You could also maintain groups in your software, which would give you more flexibility.
Regards,
Bryon
