[asterisk-users] Options for moving to * friendly Business VSP

[Al Stery]

previuos post mangled.

Hi all, 

I have a client whose business is currently running on
*@home 2.6 with Cablevision' s (CV) Optimum Voice (OV)
and 3 lines. There are going to be 4 additional trunks
needed and I'd like to move/migrate them off of OV, to
a better more flexible/open/supportive VSP. OV does
not share SIP credentials and operates a closed system
which required the use of digium tdm-400b card in
order to get the trunks into * and limits what we can
achieve. There are two parts to this plan. Here are
some of the requirements for the first part.

The current 3 lines are setup as a hunt group so
there's only one published number. My client needs to
(at least for the time being) retain that phone number
(business continuity) and CV does NOT allow number's
in exchange blocks they "own" to be ported out. Due to
this fact, I was pondering keeping one of the OV
trunks open (the main number from the hunt group), and
set it to forward all calls to the new hunt group
number on the new VSP. This would be done until such
time as the majority of customers are updated with the
new phone number.

I'm not sure how something like this would function
but my concern would be how the "hand-off" on the
forward would behave. For example, can this scenario
handle multiple incoming calls simultaneously or would
one call be dumped off into OV's voicemail system?
Also, once a call is forwarded to the new number, is
the original OV trunk freed up to accept/forward more
incoming calls? or is it tied to that call?

Part two.

Another business is merging in, bringing with it 4
lines of their own, one of which is an 800 TF number,
all currently configured via Verizon POTS serivce.
Ideally, I'd like to get those 4 trunks ported to the
same VSP also, keeping the TF 800 number and perhaps
one of the "normal" phone numbers. The requirement
here is that the LNP be done atomically, without
downtime (over a weekend for example). I don't know
whether or not this is possible.

So overall, I'm trying to figure out what some of my
options in achieving my goals here may be. I need to
know which reliable, quality Business class VSP's can
"fit the bill". Preferably one that can handle hunt
groups, or multiple channels so that more trunks can
be simply added as the business grows.

Thanks in advance for any ideas, suggestions and
advice you all can provide.
