Info about application ‘MSet’
Synopsis
Set channel variable(s) or function value(s)
Description
MSet(name1=value1,name2=value2,…)
This function can be used to set the value of channel variables or dialplan functions. When setting variables, if the variable name is prefixed with _, the variable will be inherited into channels created from the current channel. If the variable name is prefixed with __, the variable will be inherited into channels created from the current channel and all children channels.
MSet behaves in a similar fashion to the way Set worked in 1.2/1.4 and is thus prone to doing things that you may not expect. For example, it strips surrounding double-quotes from the right-hand side (value). Avoid its use if possible.
