The PBX voice gateway uses UDP packets to transmit the call control signaling between devices, it also 

utilizes the normal RTP packets to transmit the voice streams. In order to allow communications to perform  

even thoughthe PBX gateway is installed behind a firewall, the network administrator must open the required 

ports and allow related protocols to pass through the firewall. The (factory default) values for the required 

protocols and port numbers are as follows:
