We discovered that the leg_timeout will work fine as long as the SIP device has only one contact. If it has multiple contacts then it is ignored. The bridge ends in 60 seconds so maybe is using originate_timeout which defaults to 60(we do not use it in the dialplan). As a workaround for now, we may need to specify the originate_timeout to shorten the bridge timeout as 10 rings to hit voicemail is not desired. This was discovered on a box that was built a while back. I tested on a recent version from git date of 09/06/12 and it has the same problem. I will get the very latest GIT version shortly to test with.
