Asterisk, SIP, data transfert & AT modem command


My company is actually collecting data from remote “computer” using modem classic AT commands.

I wish to migrate that to a SIP/Asterisk system using Asterisk as a media gateway hosting an ISDN T0 card.

The data calls would be launch by a “collecting server” on the LAN using SIP/RTP two.

My question is :

  • Is it possible ? :smile:)
  • For the data transfert, RTP is the only option ? Is it the best ?
  • How to emulate the AT commands as the remote modem only know this language ?
  • In which format, the datas will be sent ?
  • Is there any DOCs dealing with datacall / SIP / Asterisk ?

Thanks a lot !
