Summary:                    Calls from VOIP to Dahdi requiring transcoding fail
Description: 
A call which originates on VOIP (SIP, IAX tested) and terminates via Dahdi
will fail if codec other than ulaw is used on VOIP leg of call.

https://issues.asterisk.org/view.php?id=18242 is a subset of this issue - that
issue refers specifically to
DISA having this problem, however the problem exists whenever a call is
bridged from VOIP to Dahdi.  Creating a new issue to highlight the wider
scope of the bug and clarify that it is not DISA related.

For 1.8.3 apply the following patch and you will not have any problem with
GSM/g722/g729 codecs. For other 1.8 versions the patch is similar.
