Why is it that when all users have a CO line assigned to a button, and a call is seized, or the CO line is picked up to make a call, it causes the MP3 player to stop playing because the CO line is in use. This limitation doesn't apply if the user's phone doesnt have a direct button mapped to a CO line (i.e., you have dial a 9 to access an outside number). Is there any solution/workaround to this issue besides not having a CO line mapped to a button.
