I have been trying to get the right IOS for 1751V and the MFT-E1 card. I have tried all slots (0 and 1 should work) and various software recommended by the Software Advisor: IP-VOICE-PLUS and IP-VOX-PLUS versions 12.2(8)YL, 12.2.(8)YN, 12.2(11)YV. The card is simply not visible with show version. No controller E1 is possible. Is the card dead? Or does no IOS support this combination (contradicting Cisco documentation and the Software Advisor)?
