Klaus,

    Thank you for this detailed explanation.  This is essentially what I
figured was happening.  I was able to use htable to work around it.

I guess however I am still confused as to where there is any public
documentation on this specific bit.  Had I've not been working with
Kamailio for years I would think this would confuse others.

Let me know if it is somewhere else, otherwise I will add it to the
Kamailio wiki.

Sincerely,
Brandon Armstead

    AVPs are associated with the transaction. If you "spiral" a request
    through the same proxy, then for the proxy it is a new transaction.
    Thus, when processing the request a second time, there is a new
    transaction and you do not have access to the AVPs of the previous
    transaction.

    Workarounds are:
    - store data in SIP headers and retrieve it later (ugly)
    - use htable module to store data during transaction 1 and retrieve
    it during transaction 2. Therefore you need a known "key" which is
    identical in this 2 transactions only (e.g. use "$ci$ft" as base for
    the key).

        Hello,

             I am curious if there is any documentation on how AVP's
        processing
        works in the following scenario below.

        UAC 1 -> KAMAILIO -> KAMAILIO -> DEST

        It seems that AVP's I set between UAC 1 -> KAMAILIO are lost once I
        relay back to the same KAMAILIO proxy (self)?

        Is there any documentation on why or when this would occur?

        Is there a better way to handle such a scenario?  i.e. more dynamic
        internal routing, vs relaying to self.

        Thanks as always in advance!

        Sincerely,
        Brandon Armstead
