If Realtime @ variable value is NULL or empty or contains only whitespaces then when we try to retrieve it using PJSIP_ENDPOINT we get WARNING pjsip_endpoint_function_read: Unknown property @my_var for PJSIP endpoint. And the variable is missing in the result of CLI pjsip show endpoint. This patch keeps empty sorcery extended field. ASTERISK-28341 #close Change-Id: I221fccc04cbfa2be17ce971f64ae0e74e465eea0
