My call hangs up at 30 seconds.
My internal call work normally but when i receive a external call, the call hangs up at 30 seconds.
I did all configurations in my yeastar s100 but the problem persist.
I follow this link : https://support.yeastar.com/hc/en-us/articles/360020908914-Call-Hangs-up-at-30-Seconds
but unfortunatley didn´t help.
Somebody can help me?
