Description:	Commit 356042 seems to have introduced a problem in chan_dahdi. Asterisk detects an immediate hangup on inbound calls, even though the source still shows ringing. This cycle will repeat as long as the source continues to indicate ringing. I can confirm that the issue does not occur in r355999.

By: Matt Jordan (mjordan) 2012-02-23 08:53:39.386-0600 I'm going to keep this open and make sure Terry's aware of it, but I expect this to get fixed shortly. By: Michael L. Young (elguero) 2012-02-24 15:25:10.803-0600 I was just about to open an issue about this but found this was already opened. I am attaching a simple patch which fixes this regression.  It would appear that with the recent changes for channel opaquification, the context priority is being initialized to -1 instead of 1 resulting in the dialplan never being executed. I see that chan_sip sets the context priority to 1 when creating a new sip channel and therefore sip is not affected.  I am not sure if all channel drivers should be responsible for setting this or not.  Therefore, I just set the context priority back to 1 as it was before in main/channel.c upon creating a new channel.
