[Asterisk-Users] Unable to dial out using HFC ISDN card

[Stuart Ford]

I'm running * with a bog standard HFC ISDN card using zaphfc. Everything 
seems to work, including incoming calls, but I simply cannot make outgoing 
calls. This is very odd since the same card worked with the same 
configuration in another server.

This is what I get from * debug. The only possible difference between the 
two servers that I can think of is that the HFC card is sharing an IRQ in 
the new server, whereas it wasn't in the old one. Could this possibly have 
an effect, and if so, how do I stop the card sharing IRQs with other 
devices? I've disabled everything that I don't need in the BIOS already.
