Since I am not an expert on communications, I will describe everything from the user perspective.
We had a PBX with elastix embedded and two ISDN cards in it (we have two isdn lines). The mobo of the elastix stopped working so we setup an external server with elastix and connected the PBX to it using USB (in order to use the isdn cards from the pbx).
Everything works fine except that we cannot use all 4 lines to call at the same time. We can use only two (from the first line). Αlthough we can't use all 4 lines to make calls, we can receive 4 calls at a time!
Is there an easy way to configure elastix to use all lines to make calls?
2.2.0, for the isdn cards we use the driver
dahdi 220.127.116.11 and Asterisk
If I'm missing some info, please ask to provide it.
