15.13 MGCP ALG
If you click Advanced in the top navigation menu and then select the MGCP ALG link, the following screen
appears. The UltraLine Series3 includes a Media Gateway Control Protocol (MGCP) Application-level Gateway
(ALG). MGCP is a signaling and call control protocol used by some Voice over IP (VoIP) systems. This ALG
enables use of MGCP devices behind your firewall without the need to create pinholes or custom firewall rules for
this specific type of traffic.
To enable the MGCP ALG, select Enabled from the MGCP ALG drop-down list. Then click Apply to save the
setting.
NOTE: Do not enable this setting unless your service provider instructs you to do so.
