Wanpipe is what interfaces the hardware with Dahdi/Zaptel. Then, Dahdi/Zaptel
interfaces with Asterisk. This is normal.

Personally, if possible, I'd connect one of each(FXO/FXS) on Asterisk to one of
each(FXO/FXS) on the Siemens. This allows for proper dialing between systems
and passing your ${EXTEN} as expected.

Sangoma's cards come with a half-height PCI bracket for smaller systems. To
ensure the card stays small, they use smaller jacks, RJ14 or 'handset' jacks
IIRC. Again, this is something specific to Sangoma and normal.

A few last thoughts... While OpenVOX may be tempting due to price, you'll want
to think long and hard about quality and support. Sangoma has hands down the
best support out of any of the telephony interface card manufacturers. Also,
the warranty is hard to beat. You will pay more for this, but it is worth it to
me. In your situation this boils down to the importance of the system you're
working with. For my personal Asterisk boxen at home, I use OpenVOX. They work
as expected and if they die, I'm not concerned about the 'mission critical'
nature of my test systems. On the other hand, when we ship telephony appliances
to customers domestically and around the world and want to feel 'comfy and
cozy' that things will 'just work', we install a Sangoma board.
Please accept my apologies if I sound like I'm on a soapbox trying to hardsell
Sangoma to you. Frankly, there are very few companies and products that impress
me any more, and even less so in the IT and telephony space. Sangoma happens to
be one of these few and I feel I must make you aware of it. :-)
