I can send a pre-programmed test SMS from asterisk to my soft phones, but I cannot work out how to configure my softphones to send SMS messages via asterisk. What should the Phone/URI setting in a Zoiper softphone be? I’ve tried SMS_SEND@192.168.1.76 (SMS_SEND is my SMS handling context and 192.168.1.76 is the address of my asterisk box.)
I have searched many sites and cannot find any help with settings on phones to send SMS to asterisk.
