I have FOP2 2.31.07 installed on FreePBX 13. Everything seems to be working great except for the Trunk display. I have 2 PRIs connected to the box. One has DAHDI channels 1-23 and the other 25-36. I assigned those ranges to the buttons in the FOP2 manager and restarted FOP2. The problem is that FOP2 doesn't seem to recognize the channels correctly. All outgoing calls go through the PRI with channels 25-36, and incoming can be from either. But FOP2 will only show calls on whichever PRI I assign channels 1-23 on.
This shows an incoming call on channel 36 viewed from Asterisk:
35 from-digital en default Yes
36 xxxxxxx from-digital en default Yes

This is the results from running autoconfig-buttons.sh:

And I attached a file with the screenshot of the FOP2 display.
Any ideas?

Found the answer. For those in a similar situation, when I ran a "core show channels", it showed one PRI using DAHDI/i1 and the other using DAHDI/i2. I went to FOP2 Manager and entered a 1 and a 2 in the appropriate trunk Zap/DAHDI channel box.
