If not sending sip header, can it be added to send sip header or selected column variable to asterisk dialplan?
Campaign variables: a set of variables defined for this specific campaign. They should be in the format “A:B,C:D” to set a dialplan variable “A” to “B” and “C” to “D”.
Attributes are an (optional) set of variables that are sent or read from Asterisk during the call processing phase.
