Lifespan exceeded in Voice Notification Module

Hello everyone. I hope you can help me.

I am configuring “Voice Notification Module”, when I try to do the test, and the “Notification” block of “Pipeline” is in “TEST = True” mode, I see this message:
“PHONE NOTIFICATION SYSTEM IS IN TEST MODE. The following number would have been called: +52155836 …”
(I try to configure it using the Skype Connect SIP system, a calling my cell phone)

When “TEST = False” the message is “Call has exceeded its permitted lifespan, canceling.”

I tried modifying the time between notifications, but it does not work.
