[asterisk-users] Problem with B410P

[Ex Vito]

  Could be this...
  http://www.misdn.org/index.php/FAQ_chan_mISDN#Why_does_the_L1_goes_DOWN_on_my_PMP_Isdn_Link.3F_Or_why_do_i_get_No_free_chan_even_after_group_call_from_chan_misdn_if_dialing_out_on_my_PMP_Link.3F

  Hmmm... that's a looooong link. It is the
  "Why does the L1 goes DOWN on my PMP Isdn Link" FAQ in the
  chan_misdn FAQ at http://www.misdn.org/index.php/FAQ_chan_mISDN

  In short, the telcos shut PMP links down to save on power costs, you
  need to bring them up before initiating an outbound call.

  Cheers,
