asterisk users - Nov 2004 - Incorrect parsing of 'unavailable' caller-ID from Cisco gateway

Before I raise this as a bug, it appears that * incorrect sets and reads the 
caller-id field from incoming sip packets when a Cisco gateway doesnt send 
one.

For example, in this case the caller-id (PSTN) was unavailable, so the 
resulting SIP packet was:

From: "anonymous" <sip:1.2.3.4>;tag=30A

Asterisk reads, and sets and passes this out as a caller-ID of '1234'

I would have thought Asterisk should have noticed that there wasnt a 
username portion present, and defaulted to its standard 'unknown'
setting
rather than trying to make something out of the hostname portion.

Any comments?

Actually, dug into this further, and its an issue with reading 
Remote-Party-ID headers from the Cisco in get_rpid_num, so I've raised a 
bug.
