VOIP - Dialling up to an ISDN number


[link to this post]
 
Ok, I'm a VOIP newbie, so bear with my relative level of ignorance. I don't have a VOIP based 'second phone line' through my router with my basic ADSL2 package.

I used to have an ISDN2e line at a previous address, so am familiar with that technology. Then, I could connect to other ISDN numbers digitally, to dial up servers and other data services.

I'd like to do the same with a VOIP style connection, of course, at first glance, it seems 'inside out' with the ADSL provding the service through SIP! So, Can I use something like a 'ISDN virtual modem' to use SIP (With CAPI) through a VOIP provider to dial up to an external ISDN number's data connection?

I realise I require a provider to assign a telephone number to me and to route the call to the PSTN.

Suggestions please!

I think the short answer is no. It's voice over IP so codecs are used to encode and packetise audio frequencies which are turned back into audio at the other end.

I think I've found what I'm looking for,

It's called 'Virtual ISDN.' Basically you get a router with extra sockets for the ISDN equipment.

I wasted a day so you don't have to!
