I didn't think Asterisk had modem DSP and RAS code?! Huh? At 09:31 PM 17/10/2015, Dovid Bender wrote:

Does anyone have any suggestions on equipment for our ISP that is still supporting dial up customers?
At the moment we are running 3Com Total Control 1000's but are running out of spare parts as we have failures. Given that this gear is so old trying to source spare parts is proving to be difficult.
We do have access to an Cisco AS5200 but are looking for maybe a SIP based solution that could possibly run on our VM farm? Has anyone heard of anything like that or does it even exist?
What kind of gear are you running if you still are supporting dial up customers?
Thanks in advance

No modem support - just PPP over ISDN B channels. Sent from my iPhone

I was surprised to find IAXmodem (http://iaxmodem.sourceforge.net/), which is "a software modem written in C that uses an IAX channel (commonly provided by an Asterisk PBX system) instead of a traditional phone line and uses a DSP library instead of DSP hardware chipsets." It appears to be limited to 14.4k due to patent issues and handles faxes only, but its existence suggests writing a software-only data modem should be possible. -- Aaron

That's exactly what WinModems were, back in the day. The board was nothing more than a DAA, a codec, and an ASIC to transmit and receive the raw data. For V.34, the software required about 60 MHz of clock; for V.32 bis the load was closer to 24 MHz.
