MultiVOIP is not a channel bank, it's a SIP media gateway. Look for a
Carrier Access ADIT 600 or something similar; pretty much any modular T1
channel bank should have E&M cards available. E&M will be expensive
(somewhat) no matter which route you take, because it's not something
that was deployed in massive volumes like FXS/FXO are, and it was
primarily used for trunking between large expensive PBXes.
