Summary:                    Additional codecs are added to the SDP after a
"Moved Temporarily" mesage - SIP TCP
Description: 
After receiving a 302 SIP response Asterisk adds additional codecs to the
SPD when they are not allowed in sip.conf.  The only codec allowed in this
example is ulaw.

This is a 1.6.0 system with "0013523: Trouble with Temporarily Moved"
applied
