More work on getting asterisk to work as an ISDN network terminator on the test server / 2015-02-24

2015-02-24 More work on getting asterisk to work as an ISDN network terminator on the test server
I dug up all the tools needed to test the isdn setup in the test server: an old sitecom ISDN card with HFC-S chipset, an ISDN cross cable, a fritzbox with external S0 bus and an analog phone set.

It took me a while to get all 3 channels in the ISDN card active in Asterisk, I 'missed' the fact that the oslec echo canceller wasn't loaded due to a module versioning problem. At first it showed:
root@metcalfe:~# lsdahdi
### Span  1: DAHDI_DUMMY/1 "DAHDI_DUMMY/1 (source: HRtimer) 1" (MASTER)
### Span  2: ZTHFC1 "HFC-S PCI A ISDN card 0 [NT] " AMI/CCS
  1 BRI        Clear       (In use)
  2 BRI
  3 BRI
The switch from oslec to mg2 fixed things:
root@metcalfe:~# lsdahdi
### Span  1: ZTHFC1 "HFC-S PCI A ISDN card 0 [NT] " AMI/CCS
  1 BRI        Clear       (In use) (EC: MG2 - INACTIVE)
  2 BRI        Clear       (In use) (EC: MG2 - INACTIVE)
  3 BRI        Hardware-assisted HDLC  (In use)
### Span  2: DAHDI_DUMMY/1 "DAHDI_DUMMY/1 (source: HRtimer) 1" (MASTER)
But whatever I tried: no dialtone. Time to also hook up a SIP phone to initiate calls the other way.

Maybe this will take too long to let the server-upgrade depend on it. Somewhere I also have a SIP DECT base station so I can change the setup to use SIP internally and externally and do the development with the OpenVox B200P card which is easier to switch between Network Terminator and Terminal Equipment mode.
