Hello, good morning everyone, yesterday I was making manual calls with a remote agent in vicidial, but when trying to receive a voicemail message the call was prolonged until it was cut off. Loading the trunk directly from my softphone the result was the same, the call continued until the system threw me the service not available error.
Performing another test, I dialed the same number from my telephone service, but the voicemail message can be heard without problem. I would like to know what is happening with my vicidial server because I cannot receive the voicemail message.
The configuration of the Carrier in vicidial is as follows:

(PEER)
type=friend
host=mydomain.com
username=1234567890
secret=mysecret
port=5060
dtmfmode=rfc2833
qualify=yes
progressinband=never
canreinvite=no
nat=yes
context=from-trunk
disallow=all
allow=alaw
allow=ulaw
allow=g729

Pleases do not double post. Edit the original post if nobody has answered yet.
