Hi,
Do you have an alternate peer name for inbound calls over that trunk? Verify the device name via the asterisk cli
asterisk -rx "core show channels concise"
and check the device name it has. Then add that name minus the -session suffix as the channel field in the fop2 buttons page.
Suppose your trunk is named "vitelity" and for inbound is matched as "vitelity-in", in that case, you should see some channles like
SIP/vitelity-in-A38BCD12
when doing a core show channels. If so, add "SIP/vitelity-in" as the channel field for that trunk in the fop2 buttons page.
