Does anyone know if it is possible to have a fail over for ISDN? so if the ISDN goes down, the pilot and all associated direct dials can divert to another number?
Sorry, I do not know much about ISDN :)

I think you need to ask your carrier that question.

Your telco should be able to divert calls made to the Pilot number to another number (ours can). It isn't automatic, I have to call them and get them to put the Divert on, but it is pretty instant when I do.
You need your carrier to confirm, and I think you will struggle. Most of the infrastructure out there is pretty old and doesnt support separation of numbers from physical infrastructure... you would be better to get some SIP lines terminating into a SIP-ISDN box, and going for path diversity... although if you're looking at that, I'd be dropping ISDN in favour of native SIP anyway....

ISDN doesn't go down.
What are your reasons for wanting to keep ISDN or install it? Unless you're using it for broadcast then there are pretty much no selling points any longer.

Much more stable than a lot of SIP trunks I know.

ISDN's still a thing?
Dang!

Take advice from our PABX tech but what we are told is that ISDN reliability is much higher than SIP. We have some SIP trunks and when something goes wrong, it is hard to talk to anybody at 2talk however it is cool that you can set up your own divert in their portal. We have over 200 DDI numbers on the ISDN boxes so that is probably another reason we have kept ISDN.
ISDN is a dedicated circuit resulting in a secure and private connection. It has a fixed, guaranteed bit-rate when compared to (IP) networking. One can reasonably expect better reliability from ISDN than VOIP, which is subject to packet collisions, jitter and other challenges of sharing the connection medium. You'd also usually expect better reliability from ISDN then VOIP. To say VoIP has call quality issues would not be fair. In cases where VOIP is carried over a decent broadband connection (Fibre) it will be brilliant. For best results with VOIP ensure it is carried over a resilient, business-grade broadband connection separated from your existing broadband network and that the routers, switches, cables and phones are all up to the task. ^Mike

Seriously?
In comparison with most IP networks, I’d concur isdn is a lot more stable - but only because telcos aren’t developing or touching it, they are just getting rent for a network with no development.
But I have seen isdn go down both on the neax’s, axe and nortels, enough to pretend to be concerned ;-)
ISDN is a legacy technology. Try and find a tech that can actually work on it and troubleshoot issues - they are now few and far between.
ISDN PRA (Primary Rate) is grand fathered which means no new connections. If you can find as service provider who can actually offer a new install they will often just do SIP and then put a E1 gateway at your site and it is delivered over IP / data circuit.
I believe ISDN BRA (Basic Rate) is an agency product from Spark which will go at the same time the NEAX's do

That comes down to the choice of provider and hardware.
