My "Outbound Routes" Dialplan contains the 2 lines below and I am wondering if the "set provider prefix" is safe to delete from the Dialplan because the "action bridge statement" sends the provider prefix anyways. The "set provider prefix" line is generated when we create a new Outbound Route in the GUI but seems to be useless afterwards once the outbound route is created. To me it's actually confusing because I have several alternate gateways that do not require the same "provider prefix". Please comment if it's safe to delete. Thanks.
Action set provider_prefix=xxxxxx
and
action bridge sofia/gateway/myprovider/xxxxxx1$1
Action set provider_prefix=xxxxxx
and
action bridge sofia/gateway/myprovider/xxxxxx1$1
