Grandstreams need to have Equal ( = ) signs encoded inside of a parameter

Grandstream configs can not have an equal ( = ) inside of a parameter. This will affect settings like LDAP or System Ring Tone frequency/cadence settings.

Example:
P345 = f1=460,f2=500,c=45/10-45/200;

Should encode to P345=f1%3D460,f2%3D500,c%3D45/10-45/200;

I had previoulsy went through this with OSS Endpoint Manager and rewrote part of the gs_gxp_encode. Just for reference I've included that showing which characters I found had to be replaced inside a setting value for the device to accept it.

function gs_gxp_encode($params)

{ $params = str_replace("+","%2B",$params); $params = str_replace("%","%25",$params); $params = str_replace("=","%3D",$params); $params = str_replace("&","%26",$params); return $params; }
