o chan_sip.c:

  - Improve codec negotiation logic.

  - make sure to parse SDP on re-INVITE.

o chan_zap.c:

  - If unanswered Zap channnel is hanged up wait until the calling party
    in turn hangs up (by detecting ring timeout). Otherwise next ring will
    trigger a "new" incoming call. This appears to be design limitation of
    the analogue telephone system - there is no way to reject the call without
    answering it first.
