Does the AVP get deleted at the end of a transaction? At the end of a specific dialog? If the answer is "transaction" (and I think it is), what exactly constitutes a transaction? e.g. when an INVITE is received,is the transaction completed when the corresponding "200 OK" is processed (or CANCEL)?
Also, if I have 'avp_delete("$destination")', and the AVP '$destination' has never been set, is this "bad"? or a no-op?
The above two are related. I am using AVPs to move information around in my script, and am wondering how much cleanup is necessary (i.e., delete every avp i populate, etc., etc.)

Hi Kanakatti,
all AVPs are deleted along with the transaction, you do not have do delete them explicitly. A transaction is completed and deleted when a final reply was sent back to UAC (and ACK if INVITE).
So feel free to use AVPs as much as you like and as you like - the clean-up is done automatically.
regarding the 'avp_delete("$destination")' - the function returns true in script only if there was a deleted AVP. Nothing "bad" happens otherwise.
regards, bogdan
