Basic question about ISDN addresses

Let´s suppose a BRI provided by an European Telco with a single ISDN number (address, for example 5551234) and a NT1 with 2 devices connected (an ISDN phone (voice traffic) and an ISDN router (data traffic)).

When placing calls towards this BRI (that number), is there any way to discriminate between traffic to phone and traffic to router. What I really want to know is if I need to sign up an additional number for this ISDN BRI.

Thanks in advance

Re: Basic question about ISDN addresses

If NT1 has interface for data calls and isdn phone for voice calls, then NT1 will determine the quality of call, voice and data, based on the bearer capability.

So based on bearer capability which is received, NT1 will make a decision where to forward the call.

Re: Basic question about ISDN addresses

Telco has options whether you need additional number for the BRI or not. However depends on the country you work. Ideal thing would be a word with your telco.

Thanks for your reply.

I had heared something like that, but I wanted to confirm it.
