It might be useful to make possible the use of 2 distincts coturn servers 
In my case I would like one for nextcloud and one for Galène.

Nextcloud uses the use-auth-secret 

Authentification and it turns out that I was unable to use it with Galene, event setting "credentialType": "hmac-sha1 » as described in your README file.

I can easily modify the script adding the two ports.

The installation script  do not the use the built-in  turn but install and configure coturn. Galene is launched with the « -turn auto » option. 
Would you like me to add this information ?

I am very pleased to contribute to the collective effort.
