asterisk users - Dec 2003 - Channelbank Recomendation and GS102 question

I just went through this cycle. I did go ebay and went with a Carrier Access 
Access Bank I, since I still haven't decided if this will be our production 
system and I didn't want to invest too much to find out. After fighting with
it
all day today, I would not recommend the AB1 for this application -- both 
inbound and outbound calling, because the AB1 doesn't support call
supervision
on the inbound fxo ports. And their tech support says that Carrier Access does 
not sell a model with call sup. There are various work arounds, but I think not 
matter what it would be more functional to have a channel bank that supports 
call sup. I also think there are issues with some CBs and caller ID. If you 
want caller ID make sure to ask that it is supported and with which cards.

Adtran seems to be the most recommended vendor on the list. Many refs to TA 
750s.

Hi All.

I'm working on an * configuration.  We require 8 inbound POTS lines, and 
CT1 or PRI seems like it will be
quite expensive at that level.  I've read that a T1 Channelbank plus 
the  T100P would be a (the?) way to go
for this situation.  What is the recommended channelbank for use in this 
scenario?  From searching the archives
I see a lot of suggestions to get "a channelbank" from ebay.  I would 
prefer to be able to use new products
so I can easily duplicate the setup for other branch offices in my company.

My second question relatees to the Grandstream phones.  When they are a 
member of a queue group, I get a loud
annoying ring in the handset when its in use and another call comes in 
on the queue.

Is there a way to enforce 1 call per phone in sip.conf?  Either that or 
a way to tell the GS102 to return busy when
* trys to send them a call.

Thanks in advance.

Paul M. Oster

We have an installation with 9 inbound voice channels (one is the fax) and 768K
data.  It is a Hybrid PRI.  It terminates into a T100P.  It is working great! 
The cost was better than the POTS plus data.

We're not using a channel bank.  I have one port on a TDM card for the fax
machine.

You need to use the latest CVS, it includes the work done by Paul Lieu.  It
works great.  You just configure your sip.conf according to the notes in the bug
report:

http://bugs.digium.com/bug_view_page.php?bug_id=0000408

It solved my GS BT102 call waiting ring in ear problem!

Can I ask what Telephone/Internet service provider you are getting this from?
Does anybody else have a setup like this?
