Hi,
When i use ARI with request URL to play 123 number in the channel , i’ve this error :

message: "Endpoint must be specified"

The url is : http//127.0.0.1:8088/ari/channels/100/play?media=%5Bnumber%3A123%5D&lang=fr&skipms=3000

I use Swagger

Finally i found. the good syntax when i put the p media parameter in swagger is :
number:123
