Set channel variable(s) or function value(s).
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). If you need to put a separator character (comma or vert-bar), you will need to escape them by inserting a backslash before them. Avoid its use if possible.
