HDX ISDN settings

Hi All,

 

I recently installed a Quad BRI ISDN interface to our HDX7000. After some fiddling around I got it working; it appeared I had to omit the leading '0' from the areacode. So f.i. if I want to do a national call to amsterdam I would call '020-1234567', but with the HDX ISDN I have to call '20-1234567'. It's doable, dut strange for people used to using a phone.

 

The other thing is: all the lights on the BRI are standard off. According to the HDX docs this means something is wrong. All the NT1 boxes have 'line ok' lit and when I attach a ISDN-phone, the lines work perfectly. Nevertheless I am able to make ISDN calls with the HDX (without the leading '0' as mentioned) despite this deviation form the docs.

 

Then when I call to a particular number which is redirected through a bridge to a SIP endpoint, first the HDX states calling through ISDN and then it switches to SIP without ever getting a real connection to the other system.

Other ISDN callers have no problem calling the bridged endpoint and my HDX can call other ISDN-connected systems (some of which I do not know wether they are bridged or not).

 

Finally, when I use my cellphone to call the ISDN-numbers of my HDX I get to hear 'this number is currently unavailble' while the lines are free. And I have no problem making an ISDN videoconfernce call to the same number.

 

Well a lot of input, probably with very different causes, but maybe and hopefully some of you recognise issues due to configuration errors which I might have made or other things I might check or do.

Thanks in advance for any thoughts on this matter!

 

kind regards,

Fred.
