I am planning to tie a Nortel DMS switch with Asterisk PBX via an SS7 trunk.
I want to use Asterisk only as a Voicemail/SMS storage Box.
I have been told that when a person leaves a Voicemail than an SMS needs to be sent to the switch ( probably a special number) to indicate to the called party that there is a voicemail waiting. Which Asterisk SMS is best suited to address this scenario i.e. on leaving a voicemail it should trigger the SMS portion and that SMS should confor with any standard requirement for using SMS as a voicemail notification tool. Please keep in mind that I also plan to use SMS for regular SMS message exchange.
