[SR-Users] Keeping track of routing/dialog attribute value pairs

[Dirk Teurlings - SIGNET B.V.]

Hello,

Throughout the routes of kamailio we use multiple variables. These 
consist of $var, $avp, $dlg_var and probably more. What's the policy for 
these variables when used. When, if even, are they being cleaned up 
after a call has been terminated.

Is this something we need to be doing ourselves with functions like 
avp_delete("foo")?

Many thanks!
Dirk
