Hi. I recently bought a B100P card and use it with Elastix. I want to connect a simple ISDN phone on the card so I've setup jumpers (SW1 to the left & SW2=ON) and misdn-init, mISDN, and misdn files to NT mode ptmp. The card is recognized by elastix but I have no tone from the phone. When I do misdn show stacks I get:
misdn show stacks
* Port 1 Type NT Prot. PMP L2Link DOWN L1Link:UP Blocked:0 Debug:0
I have followed every guide available online but this have given me only headaches without any result.
The ISDN phone I am using is a DECT phone and has it's own power supply. Well I have tried everything to forward the SSH port to my router, disabled firewall, setup dyndns etc but when I try to connect from the outside it says "connection denied". Even tried to change the ports through httpd but still nothing. It is merely impossible to connect from the outside. It just refuses every connection. Do you think it is a router problem or Elastix has some kind of feature to refuse connections from the outside?
After playing a bit with every single guide I could find online I have managed to make the phone make calls (ISDN phone dials other extensions and outside line through 9 OK) but cannot accept calls. Any ideas here?
