I am new to this forum.
What brings me here is the need for a GSM gateway.
Basically I have an analog Line (ISDN) which I want to change into GSM, allowing me to save a few.
I would need this gateway to have at least support for:
- 1 SIM Card (GSM)
- 2 FXS (I want to keep the old phone, and connect an alarm system to the 2nd input)
- LAN (Connection to Asterisk)
- VoIP (This would be a great addition, allowing VoIP to be established over the GSM line.
Can someone provide me a few of the most common options so I could choose based on price?
Also, since I am new to this, is there any Gateway which already includes Asterisk installed?
