Look at a Sip or IAX interface like this:

Quintum AXG2400 24FXS Analog VOIP Gateway 501-0145-00

The Tenor AXG2400 Twenty-Four Port Enterprise Gateway is designed for analog
station side applications. It is used for interfacing analog devices such as
phones, FAX's, keyswitches, or PBX's to the VoIP network. .

Or this one:

Audiocode MediaPackl MP124-FXS Analog Gateway with 24 FXS Lines - SIP
Protocol

These run about $2K and have 24 ports.   Better price per port than T1 &
channel bank combined (unless the CBs are used).
