<div dir="ltr"><div dir="ltr"><div><div><div><div>I've searched back in the VoiceOps archive for a
discussion about redundancy, and it has been a while. I wanted to spark
a useful discussion for the list, and hopefully figure out one issue
we're having. <br></div><div><br>We use a SIP provider that connects
to our IP-PBX in our datacenter. We have standard redundancy within our
PBX infrastructure, but we want to build out redundancy for if our SIP
provider has an issue reaching our PBX (could be DNS issues, network
issues, primary & backup datacenters down, etc.). <br><br></div>If
our SIP provider is unable to reach our PBX, they offer a 'failover
route' where it can route to a standard 11-digit DID. For individual
employees' DIDs, we're just routing directly to their cell number. The
issue is routing our high-volume DIDs -- the main IVR, the call groups,
etc -- to simultaneously ring a group of cell numbers. <br><br></div>From our research, the best bet seems to be to utilize <a href="https://www.evoice.com/feature/included/simultaneous-ring" target="_blank">eVoice</a>,
and setup up a new (unpublished) DID to ring ~15 cell phones using up
their 'Simultaneous Ring,' and then forward our high-volume DIDs to the
new eVoice DID. <br><br></div>Does anybody have experience with this?
Am I going about this in an asinine way? Is there a better vendor? Are
there other ways that you've built out inbound redundancy for VoIP
solutions you've deployed? <br><br><br></div><div>Thanks, <br></div><div>Jacob<br><br></div><div>P.S.
To add to discussion - While our SIP provider were to be disconnected
from our PBX, lost inbound faxes are also a concern. I'd then use
something like <a href="https://www.efax.com.au/web-fax-pricing" target="_blank">eFax</a>
to take the inbound faxes to a distribution group email (after testing
it works while forwarded from our SIP provider, who does use T.38), by
setting a backup route for our fax DIDs to hit our new eFax DID. These
two measures would ensure minimal missed calls/faxes while critical
infrastructure was down. <br><br></div><div>eVoice Link: <a href="https://www.evoice.com/feature/included/simultaneous-ring" target="_blank">https://www.evoice.com/feature<wbr>/included/simultaneous-ring</a> <br></div>eFax Link: <a href="https://www.efax.com/features" target="_blank">https://www.efax.com/features</a></div></div>
