Greetings,
We are getting ready to migrate multiple IVR applications to multiple
PRIs hosted by my telco's DMS switch.
Each application will have a unique lead number with every lead number
present on every PRI and even call distribution across all PRIs. The
IVR software uses the DNIS dialed number to route each call to the
correct application process on the correct server.
In the present system, concurrent calls are capped by the number of
POTS lines in an analog hunt group. We are migrating from this ancient
system to a stack of servers running IVR software. Some of those
servers have PRI cards to receive the calls.
We must have a boundary between the applications to prevent one app
from taking over all available B channels. I want to set a different
concurrent call limit for each DNIS dialed number. Is there a
straightforward way to do this with a DMS switch?
The max-concurrent-calls parameter I'm thinking of would certainly be
set per dialed number. It also might apply per switch, per
index-group, or per PRI. Any of those would work fine as long as it
interoperates correctly with even call distribution.
Even if there is not a single parameter that corresponds to
max-concurrent-calls, there may be a way to do this by setting several
parameters and/or mappings creatively. Please think about it and let
me know if you can see a way to do it. Email me direct if you would
like to chat out-of-band.
What I'm laying out here seems perfectly ordinary to me. But I'm an IP
not a voice guy. Does anyone see any gotchas?
For example, in surfing the question I just asked above, I read a
chilling account from someone who was sniffing D channels and seeing
calls with empty dialed-number fields. Am I right to count on DNIS?
My naive understanding is that the dialed-number field is used to route
the call and therefore a call cannot arrive without this field filled
in.
