[Asterisk-Users] Asterisk + NEC IPK 192 integration

[Dustin Rue]

I am currently attempting to get Asterisk working with our existing NEC IPK
192 system.  The * box has a Wildcard X100P clone card in it and is hooked
to an analog port on the NEC system.  The analog port is shared between an
elevator phone and a credit card machine.  I have one SIP extension
configured in * which the softphone on my Windows PC is registered to.  With
the softphone I am able to place calls using the demo dial plan and to my *
box running at home over IAX2.

With this setup I am also able to dial an extension from the * box to any of
NEC extensions (including the outside world) but I'm unable to do the
reverse.  Instead I just get a really weird ring tone and the X100P card
never hangs up.  I have to reboot the whole * box to get everything back to
normal.  Other times the X100P card stays offhook and * will continuously
ring my softphone even though there is no call coming in. Any tips on what I
could try?  Is the NEC expecting something other than kewl start or is it
because it's sharing the line with other devices?

I have very limited knowledge with phone systems and the terminology and an
even more limited budget (hence the $17 X100P clone).  I have managed to
setup a dial plan for a few softphones but never anything that is integrated
into "the real world."  I have two goals in the end, to replace a phone
system at one site and integrate it with the NEC system and to get voicemail
setup for another.  Getting the second site integrated with our main NEC
system would just be a bonus, but not required.
