Hi. the fax show version does not work since i am not using the digium
modem.
the iax2 show peers is the command for me and the output is:
PBX*CLI> iax2 show peers
Name/Username Host Mask Port Status
Description
iaxmodem/iaxmod 127.0.0.1 (S) 255.255.255.255 4570 OK
(1 ms)
1 iax2 peers [1 online, 0 offline, 0 unmonitored]
PBX*CLI>
the problem is that in logs i am getting errors and i do not know how to
fix it.
