Sure the TDM400P will never do V.90 modem. But I had some extremelly interesting results ...
Modem ---> TDM400P ---> Asterisk ----> TE405P ---> PRI E1 ISDN ----> PSTN ---> PRI E1 ISDN -> Cisco AS5300 RAS I got 33.6kbps reliable connection Crazy test follows. Modem ---> PAP2-NA ---> Asterisk ----> TE405P ---> PRI E1 ISDN ----> PSTN ---> PRI E1 ISDN -> Cisco AS5300 RAS I got 50.3kbps reliable connection after tweaking PAP2-NA, between the PAP2-NA and Asterisk, there's a FreeBSD NAT/QOS appliance. Asterisk is on cheap but high quality hardware (Intel desktop mo-bo, Intel processor). Final config: PSTN ----> PRI E1 ISDN ----> TE405P ---> Asterisk ---> TE405P ----> AS5300 RAS When I dial from an analog line, I'm getting the same performance we would from the ISDN hooked up directly to the AS5300... Still need to test dozens of simultaneous modem calls. We still have the choice to have another AS5300 splitting the ISDN between the RAS and Asterisk, but that's our last resort. For now the production RAS is still on the other (to be deactivated ISDN). Configure Asterisk E1 stuff well and it works real well. I really wasn't expecting results this good.
