i have a problem in incoming calls with the external sip trunk.
vitalpbx stn is 5001,and did number is 55555001,
when i set the cos of the trunk “all permission”, external pbx can call 5001 by the trunk,but can not call 55555001.
when i set the cos of the trunk “trunk default”,external pbx can call 55555001,but can not can the 5001.
why? how can make it together? i mean that external can call 5001 and 55555001?
