Hello prefixers,
I found this wonderful little app just yesterday and I’m really thrilled about it. I have been looking for something like this for about 6 years and now I finally have it. Thank you so much!
Now on to my problems with configuration (I couldn’t find any tutorial):
My DSL and mobile Carrier offers free calls between all their costumers no matter if landline to landline or mobile to landline and vice versa. I have set up my AVM Fritz!Box to accept call through when I’m sending my mobile caller ID and enter a PIN. This part works fine.
Now I want to place ALL outgoing calls from my mobile via call through EXCEPT when the number is registered with my provider (landline or mobile) AND a member of the Google contacts group XYZ.
The (Google) contacts in my Andoid device all look like this:
+COUNTRYCODE-AREACODE-PHONENUMBER
(+49-30-12345678)
If the number is not stored in my contacts yet I usually type in just the number including the area code but not the country code and don’t add special characters like “+” or “-“
In this case they are usually not registered with my Provider and have to be placed via call through if they are landline and directly if they are mobile.
This is my goal:
- Call all cell phone numbers directly without any modification
- Call all numbers (landline and mobile) that are registered with my provider (group “XYZ”) directly without any modification
- Call all other numbers with a modification to use call through
I have been (unsuccessfully) trying to set up rules like this:
#1 mobile direct without modification:
Number matches: (\+491*).* | (\+49-1*).* | 01.*
Number in contact list: Either
-> do nothing but call
#2 modify number (call through) if from contact list but not a member of the group “XYZ”
Number matches: (\+491*).* | (\+49-1*).* | 01.*
Number in contact list: Yes
Not a Member of the Group “XYZ”
Remove: \+49-
Add prefix: MY LANDLINE PHONENUMBER,PIN,0
#3 modify number (call through) if not from contact list
Number matches: (\+491*).* | (\+49-1*).* | 01.*
Number in contact list: No
Remove: \+49-
Add prefix: MY LANDLINE PHONENUMBER,PIN,0
The above rules don’t work for me.
I have been searching the web for hours to get the regex right but I guess I’m not exactly a math genius

Maybe it's really easy in the end and I just didn’t see the forest because of all the trees?
Thank you so much for even reading this far! I’d really appreciate a little help from you experts.
Best regards
