Re: Solution Modem analog and ISDN

There are three different interface devices for connecting analog modems:

wic-fxs

ATA186/ATA188

VG248

Do not expect speeds greater than v.34. Higher speeds may be possible but are not guaranteed. I believe that you must also use modem-passthrough. When last I heard modem-relay was not supported.

Don't have any answers for ISDN modems.
