EVAL()

Synopsis

Evaluate stored variables

Description

Using EVAL basically causes a string to be evaluated twice. When a variable or expression is in the dialplan, it will be evaluated at runtime. However, if the results of the evaluation is in fact another variable or expression, using EVAL will have it evaluated a second time.

Example: If the MYVAR contains OTHERVAR, then the result of ${EVAL( MYVAR)} in the dialplan will be the contents of OTHERVAR. Normally just putting MYVAR in the dialplan the result would be OTHERVAR.

Syntax

EVAL(variable)
Arguments
  • variable
