Subject: [PATCH] Calling name not successfully processed on inbound QSIG PRI
 calls from Mitel PBX

The alternate form of the Q.SIG Name sequence that allows manufacturer
extensions for CallingName, CalledName, ConnectedName, and BusyName was
not consuming the next ASN.1 tag.  The code that processed the ASN.1 Name
structure was then using a stale tag value.  The stale tag value was then
rejected with the "Did not expect" message.

I have added a test case using the supplied PRI debug output to the
rosetest utility to verify that this alternate encoding is tested in the
future.
