AudioCodes determine IP

Here's a trick on an AudioCodes box that isn't talked about lot, the voice configuration menu.

There are a bunch of features.  

Plug a phone into the FXS port and dial ***12345 (that is the default login).  You might need to disconnect the ethernet on it in a situation where an ITSP might actually be working, it will probably try and dial that number.

You'll Hear "CONFIGURATION MENU" if it has worked

Dial " 1#  " to get the Current IP 

Send Asterisk voicemail notifications via Gmail

Here is how you can make asterisk use GMAIL to send voicemails

Tested on Issabel distro on Asterisk 16.6.1

1> Login to your Gmail Account (via browser)

2> Set the "Less secure app access" to "ON".  The fast way is to click on this URL after you have connected to GMAIL

You will probably receive some google alerts that this is been set.

3> Install POSTFIX

yum -y install postfix mailx cyrus-sasl-plain
4> Edit the password file and put in your gmail credentials.  You can use VI or NANO (install instructions for nano below)
If you aren't familiar with Vi, you can install NANO using the following command
yum install nano
Put in the following information, alter it with your credentials for gmail.  This file is going to be encrypted after a successful test so dont worry about your credentials being stored in clear text, it is only for a few minutes.
5> Now we hash (encrypt) the password file so that it can't be stolen.
postmap hash:/etc/postfix/sasl_passwd
6> Edit the file /etc/postfix/

Paste in the information below and save
smtp_sasl_auth_enable = yes
relayhost =
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_security_level = secure
smtp_tls_mandatory_protocols = TLSv1
smtp_tls_mandatory_ciphers = high
smtp_tls_secure_cert_match = nexthop
7> Reload the mail service
8> Send a test message from the CLI
[root@issabel asterisk]# mail
Subject: This is an email test
This is a test.
If everything worked correctly, you SHOULD get an email to the email account you used via your Gmail Account

If NO email showed up, you can look at the mail log /var/log/maillog
