[cisco-voip] 1760 as a IPIPGW (CUBE)

[Nick Matthews]

You can accomplish something very close to CUBE, but no, it will not
be a CUBE.  There isn't any IPIPGW code for the 1760.

The commands exist in non CUBE software packages, but there is a
slight variation in many of the corner case scenarios that makes it
work more like a SBC instead of a terminating gateway.  The commands
'allow-connections h323-to-h323' and such have been around for
CUBE-like scenarios like routing calls between two CMEs to CUE
(SIP-H323).  This behavior is different from actual IPIPGW
implementation.

As well, there were large improvements in CUBE in 12.4(20)T,
especially with SIP.  If you're doing SIP at all 12.4(20)T is a good
place to start at, and since the 1760 is being phased out, 12.4(15)T
is the last release for that platform.

Short story - it's not a CUBE capable router, but you may get lucky
and have it work if you're dealing with the simple standard-case
situations (not supplementary services).
