The Internal Modem card allows up to 12 simultaneous V.90 (56kbps) analog modem calls into the IP office.  

  • The IP403 will support only up to 4 simultaneous modem connections.

  • The IP406 V2 and IP412 will support up to 12 connections.

  • This card is NOT supported on the IP406 V1, only on the new IP406 V2.
