Hello Harry,
My experiences are as followed:

The MTP-Layer seems to be implented fully. At least to Layer 2, not sure
about Layer 3, but I don't use things as failover, so I cannot tell for
sure.
ISUP is not completely implemented. The most message types/features are
there and working, but AFAIK some things are not there, but also nothing
that I would need. When I first tried chan_ss7 in late 2005, there
wasn't an implemantation of CCR test, but we let that implement by a
developer and since then all features that we need are there.

Work as they should. Nothing much to say about that.

I think it got transmited, but I am not sure, if this gets somehow into
other channel types like SIP.

The calling number is always in ISUP messages. Only if one bit is set,
you must not show it to the end point (the user). Asterisk with chan_ss7
can set this bit. I don't know if COLP works. Never testes this.

Never done anything into that direction, so I cannot tell.
In overall I can say, that it works stable since about four month in a
friendly-user test.
