what is the fritzbox-in node? it's the one failing with an internal error - hard to say what the internal error is without knowing what node that is.

Node Ids are the same:

hence it must be the fritzbox-in node causing the problem

You are using node-red-contrib-fritz? Be aware this node has not been updated for more than 5 years now. While most of the functions seem to work, others fail with no obvious reason.  
I only use it to retrieve network information, not to initiate calls.

##### First ideas for troubleshooting:

Do your credentials entered in fritz-config node work? Is the specified user able to login using your password?

When using a Fritz!box node, are you able to retrieve the services (select your device, and click on the search icon next to "Service")?  
Does this work as shown below?

Hi,  
I tested your flow with my fritz box 7490 Fritz os 7.61

first you have to use a dummy user name if your access is only with password to fritzbox,  
second you have to enable dial aid in the fritz box  
in German "Telefonie-\>Telefonbuch-\>Wählhilfe" -\> "Wählhilfe verwenden" and select a phone

if this dial aid is not enabled I also get this error message "Action failed with error: Internal Server Error"

if I dial the number from Noder Red,  
my Smartphone is ringing, the I hear the text "ihre verbindung wird gehalten" \<-\> "your connectoion is on hold ?"  
then the telephone at home for which the dial help was configured is ringing,  
if you accept the call from this phone at home, a connection is made between this phone and your smartphone.

Hi Tom,  
I do not understand ".... use a dummy user .."  
The only user on the FB is "Alois" + Password. If I do not use them in th FB access error msg is: "Action failed with error: Unauthorized"  
According to you I've enabled "... Wählhilfe". I've tested it and FB makes a call to the selected internal phon.  
Whatever I've tried it ends with "Action failed with error: Internal Server Error"

Could you pls send me your flow which works at your side?  
b.r Alois

Because of dummy user,see the info in the first screenshot.  
I think the access rights to your fritz-box are ok.  
I don't know if this is necessary, but  
I have my smartphone number also in the telephone book.  
additional requirement  
"noch eine Anforderung"  
"Zugriff für Anwendungen zulassen" see last screenshot

Now it works!

- I did not sent an object to the Fritz-node (unsing the funktion-node). Sent an String using the inject-node.
- Did not activate the "Wahlhilfe"  
Thanks al lot!
