Provider Rules
Provider Rules transforms E.164 compatible number to any number format Provider requires.
Description
Different providers expect different number formats from you. You can send them whatever they want using Provider Rules.
They can be reached pressing 
icon next to some provider in Providers window:
We see similar window as with Localization. The rules to manage Provider Rules are identical to Localization management which are covered here.
Let's say our provider expects to get number with technical prefix 89765#. We can do this in following way:
That's it – very simple. Now every number which will be sent to this provider will be transformed adding our created tech. prefix.
Example: 37063042438 should be sent to this provider, so this rule will be activated and number 89765#37063042438 will be sent to provider.
REMINDER: You can check if Provider Rules are applied correctly in Call Tracing
CallerID overwrite for Provider
(This functionality active from app_mor.so v0.7.41)
Sometimes Providers only accepts calls only with some CallerID.
It is possible to overwrite any CallerID before sending call to such Provider.
In Provider Rules (for this Provider) setup such Rule:
In this example all calls going to this Provider will have CallerID = 9999999999
Destination same as received
(This functionality active from app_mor.so v0.7.50)
If you want to send exact number to Provider as received, set Cut = '-' (minus sign as shown in screenshot).
That way same number which comes to MOR leaves MOR:
