Is DID on analog line possible ? ( my telco is qwest) . Just

there is any way to test it on anlog wcfxo cards.
Another approach is to use a CTPX or Exacom unit to convert the DID or
2-Wire E&M signal into a signal appropriate for a Digium FXO port
(converting the DID signaling info into DTMF after Asterisk takes the
FXO port off-hook).
See:

I used such convertors about 15 yrs ago with a dialogic D41 4 port ISA
card. For software testing I used a panasonic 6x16 switch without the
convertors. The way I would test DID handling is that I relaxed the
timing during the test. I would dial an extension connected to the
dialogic card and soon as it answered send 4 digits. To make this easier
I got a phone with a lot of autodialer buttons.
Since Apu mentioned this is needed for a test I wonder if he can do that
with DID's provided via SIP/IAX2? Last time I checked analog DID trunks
were expensive both NRC and MRC.
