For example...from the softphone we would dial &quot;12345#0123490&quot;....this needs to actually dial the number &quot;0123490&quot; and use the number &quot;12345&quot; as the outbound CallerID display.

    Hi we have a FreePBX Voip pbx which is running quite okay;Everyhting is functional and working but we often get calls from fony/faxe extensions .It happens that on 1 extenions like 15 lines are ringing all at once from extension 100Last week we got calls from extenin 33400 then 33500 then 33600 then 33700 etc...I disconnect the phone so the ringing stops. After 1 hour I connect it again now calls frol 44100 > 44900Disconnect the phone again.1 day later no calls anymore. If I pickup a call nothing happens. It is like a bot or something trying to do something;Who can fix this or knows what to look for?When I check the CDR log I cannot see the originating call. I cannot tell when it happens or why.But it is really annoying.
