Description Ilan 2016-06-20 14:14:04 UTC

Hello

I've been using the latest code from git in order to use the voice features, the problem is that when I hangup an incoming call, I lose the bearer services.
Using the secondary serial port and sending a manual AT+CHUP command the bearer services never stop working, but when invoking the hangup method from the Voice interface a disconnection happens as can be seen in the following message.

Comment 1 Ilan 2016-06-20 14:16:14 UTC

ERRATA:
The hangup method is from interface Call and not from interface Voice.

Comment 2 Ilan 2016-08-12 11:13:18 UTC

Hi, 

Just an update: sending the AT command "AT+CHUP" through the Modem.Command method does not disconnect the bearer.
