Description:When doing Originate request using the Manager Interface the Channel attribute of the request contains the channel specification. The buffer for this data is AST_MAX_EXTENSION long, which is 80 bytes only, while for example a SIP channel specification can contain not only extension but also authname (can be quite long), password, md5 secret (32 bytes), hostname (MAXHOSTNAMELEN = 256) and port (5 bytes). So the buffer for SIP channel specification should be at least 462 bytes:

 channel name (3 bytes) + extension (80) + password or digest (at least 32) + autname (about 80 bytes) + hostname (256) + port (5) + delimiters (6)

The patch (against trunk) attached.

Provide more space for all the data which can appear in an originating
channel name.
