Please note that you have to disable the autoprovisioning option on your OBi110 otherwise the settings will be automatically resumed to the orginal settings from OBi portal server.
I used the Zoiper software + OBiAPP to make a outbound call as follows:
<speed dial> **8 + < PSTN telephone number >
The first asterisk is removed by the firmware 1.2 then rule 1 is fired. I am able to make a non-primary line PSTN call using one-stage dialling method.
I have tried your suggested one-stage OBL but failed. A voice message with "There is no available service to complete your call" returned.
Referring to the above code in RED, it seems <speed dial> **8 would just initiate a call using its own PSTN line instead of making a call using remote resources on another OBi110. Am I missing settings on other configuration pages?
It would be pleased if you could make some screen capture on both local and remote devices for our reference. Thanks
