Review request for Asterisk Developers.
Bugs: AST-1302
https://issues.asterisk.org/jira/browse/AST-1302
Repository: Asterisk
Description
-------
Establishing an IAX2 call between Asterisk v1.4 and v1.8 (or later) results in
an unexpected call disconnect. The problem happens because newer values in the
enum ast_control_frame_type are not consistent between the branch versions of
Asterisk.
For example:
1) v1.4 calls v1.8 (or later) using IAX2
2) v1.8 answers and sends a connected line update control frame. (on v1.8
AST_CONTROL_CONNECTED_LINE = 22)
3) v1.4 receives the control frame as an end-of-q (on v1.4 AST_CONTROL_END_OF_Q
= 22)
4) v1.4 disconnects the call once the receive queue becomes empty.
Several things are done by this patch to fix the problem and attempt to prevent
it from happening again in the future:
* Added a warning at the definition of enum ast_control_frame_type about how to
add new control frame values.
* Made block sending and receiving control frames that have no reason to go
over the wire.
* Extended the connectedline iax.conf parameter to also include the redirecting
information updates.
* Updated the connectedline iax.conf parameter documentation to include a
notice that the parameter must be "no" when the peer is an Asterisk v1.4
instance.

Testing
-------
Without the patch the IAX2 call gets disconnected when the call initially
connects.
With the patch the call stays up.
