Asterisk,GMS gateway

Looking for someone design a solution for me, which will route calls from gms network to normal numbers, voice mail to email facility and can manage text based messages in web interface. I have worked in asterisk pbx before so do know voice mail to email is possible, challenge is in combination with GSM gateway and call route from GMS network to another network I need access sms console when I can reply messages. Plan is access forward calls based on time schedule and access sms messages from remotely while traveling.
