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 ? )
- 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 !
