You can change/set the From-addresses in FreePBX to something you want.

Change the address in Admin » System Admin. To the right, click on Notification Settings, then fill in the From Address.

These are set up from within Asterisk, and are located at Settings » Voicemail Admin. Click on the Settings link, then scroll down until you find serveremail. Change it to whatever you want.

Make sure the following directive is set in your provisioning config:

<specialEvent voIpProt.SIP.specialEvent.checkSync.alwaysReboot="1" />

You find this in sip.cfg, or you can set it in your own configuration (mine's called aaps-settings.cfg, but that's just an arbitrary name).

Notice
When setting this variable in your own configuration, be sure that it's set in the right context, like so:<localcfg> &l  ...

The trouble with PSTN lines is that the CID has to be transmitted in-band, and there are more than one standard in doing this. On top of that, there are small differences between the various Telcos on the planet. And finally, to make things worse, documentation about it, is sparse and scattered at best.

The settings displayed usually go in /etc/asterisk/zapata.conf (either directly, or by inclusion).

How CID is handled is defined by the following variables:

cidsignalling: tells how the CID signalling occurs, can be bellcore (mostly US hardware), v23, or dtmf.

cidstart: specifies how the start of the CID transmission is indicated. Can be polarity (the polarity on the wire is swit  ...
