[Asterisk-Users] Re: [Serusers] SER IP PBX for multiple clients

Waldo,

How do you let your customers manage 'their' PBX. I too have a setup
like you. However, I installed a * server for each customer, via
vserver. I'd like to now what kind of software/webbased package you use
for this.

I also have SER installed as a front-end server for the * servers. But,
as I'm still not very into SER, don't know exactly how this fits in.
Should I use SER only as proxy, or also as a registrar server (with the
same problems as you describe)?

Hope someone at this list is able to help us! 

Regards,
Ronald

Onderwerp: [Asterisk-Users] Re: [Serusers] SER IP PBX for multiple
clients

lqbal,

I do plan on having alot of users. Two markets I'm trying to get some
volume users from are: residential consumers and business users.  
Residential consumers should get basic line services such as their own
DID, voicemail, caller-id, call-waiting, three-way calling, and
basically, all the standard features you get from companies like Vonage,
etc. This particular market base will have a higher volume than business
users.

Business users will get everything residential consumers get, plus
additional features. Features such as, automated attendant, extension-
to-extension calling, company directories, etc.

I guess I would need to have SER and Asterisk work in tandem. Now, what
should be the correct approach in assigning responsibilities to both SER
and Asterisk respectively? Should SER be used strictly as proxy to
Asterisk, may be also registrar, and NAT helper, and then have Asterisk
handle all the calling plans, features, enhanced services and SER will
simply forward everything to Asterisk? Can you or someone advise as to
what would be the more robust/scaleable architecture to deploy this?
Needless to say, it is imperative that I get proper CDR from either one
or both systems in order for me to properly bill our users. I don't know
which of the two platforms has a more robust/customizable call logging
facility.

I took the liberty of cross-posting to the Asterisk list in order to get
some of their feedback as well.

Thanks,
Waldo
