[Asterisk-Users] Need Help with SIP/H323.

[Rafael Gonzalez Lomeña]

Hi list,

   why I cannot hear voice when I call from a SIP telephone (Budgetone and others) to a H323 telephone (several models)? 

   could anybody please give any idea to solve this issue?
  
   Please, let me know.

Thanks in Advance.


N.B.

  The configuration for "extensions.conf", "sip.conf" and "h323.conf" files  are:
