It not possible to use 0.0.0.0 for on profile. however, you can create more sip profiles for each of your interfaces. Search freeswitch-users archievs then you will find similar topics.

Hello,
 
  I am trying to run FreeSwitch on a machine which has more than one interface, all of them should be used for SIP. The FreeSwitch binds only to the first one. I tried setting bind_server_ip to either "auto" or 0.0.0.0 but it doesn't help.
 
Any idea what to do?
 
                        Thanks! _Yehavi:
