microphone disabled in intercom calls

[JimPatch01]

We've got CUCM6.1. Just set up intercom function for testing and have found that the mic is muted on the called station and that the mute button is disabled. Any thoughts?

We figured it out.. It was a procedural issue with answering the line on a 7921
