[asterisk-bugs] [JIRA] (ASTERISK-25739) IAX2 - No native bridge on peers when encryption=yes

----------------------------------

    Resolution: Not A Bug

This is not a bug. When encryption is in use the media has to be decrypted and re-encrypted with the new key. IAX2 does not provide a mechanism to exchange the required keying material between both sides to allow a native transfer to occur.

> Seems that native IAX2 transfer does not work when encryption=yes is set on peers.
> Box A : Asterisk 1.8.32.3
> Box B: Asterisk 11.17.1 
> Box A is calling box B.
> Then box B transfers call back to box A.
> When encryption=no is set on both peers, everything is OK
