Steve:
Unless Asterisk is on the public side of the Internet, you will run into
problems if the UA (SIP phones) are behind a NAT.
In the scenario you presented, I think SER would be used for all calls
between SIP phones and they would only go to Asterisk when you need to
Gateway into the PSTN some of the calls.

Uriel

Hi,

I've just read the postings regarding the interworking between * and SER.
As these persons seem quite knowledgeable on this, I would like to have
their advise on my planned installation:

- I have broadband cable access
- I plan to install a SIP-aware router
- I plan to install a Linux server with Digium analog IF card(s) for
connection to my analog line (incoming and outgoing)
- I plan to install Asteriks on that server
- I plan to install a SIP-proxy,registrar on the same server (I've been
looking at iptel's SER)
- I plan to use the Budgetone SIP phones
- I plan to have a public (static) IP address

All this to have my own little phone company for me and my family/friends
as we are spread over Europe (high international phone costs!). Calling
eachother on our SIP phones and also being able to use eachother's PBX's to
make local calls. I would host the SIP Registrar (in stead of outsourcing).

My main question lies in the interworking between iptel's SER and Asteriks.
Not only on the configuration side, but also on the network side (here I
mean: can both run on the same server, or do they need to have different IP
addresses, ...).

Does anybody have a diagram or any practical guide on how to install this?

Thanks,

Steven
