We have come up with a procedure for Adtrans on how to configure for multiple paths for both Voice and Faxing. This is based off the documentation from Adtran.
If you need assistance with how to log into the Adtran CLI, please refer to the appropriate article.
#1 – change GUI and telnet password
#2 – draw a diagram and label the ports/trunks/groups with proper T01, T02 etc
On GUI – set trunk accounts/groups with names
faxtrunk
voicetrunk
custpbx
in telnet->enable->config
voice ani-list faxes
ani {a fax ani}
ani {another fax ani}
....
exit
voice trunk-list faxtrunk
trunk T02 (or whatever Tnn is correct for faxtrunk)
exit
vocie trunk-list voicetrunk
trunk T01 (or whatever Tnn is correct for voicetrunk)
exit
voice grouped-trunk custpbx (This MUST be the existing turnk GROUP name)
permit list voicetrunk
deny list faxes
exit
voice grouped-trunk faxtrunk
permit list faxes
deny list custpbx
deny list voicetrunk
exit
voice grouped-trunk voicetrunk
permit list custpbx
deny list faxes
exit
