Hi, I've configured a connection using E&M cards on Cisco 2900 Routers using LMR. The configurarion works great, the only caveat that I have found is that every time you boot the router, the LMR trunk set the e-lead to ON eventhough theres no m-lead applyed. The only way to "reset" the e-lead (I mean to switch it to OFF) is forcing m-lead signal and then take it out... I must do that on both sites fisically so is not really an option. Once I do the reset by forcing M on the port everything works just as expected.
Why my e-lead starts seted as ON?? Is this a normal behavior??
I found the comand "bootup e-lead off" but it has no effect so far.
Any advice on how can I avoid the e-lead to go ON every time the router boots up??
Here is site A config,

Here's the output of the "show voice lmr" command on both sites just after a reload.
