Learn how to connect a SIP trunk to FreePBX for incoming and outgoing calls with zero fixed cost.\u00a0<\/strong><\/p>\n

$\"\"$ <\/a><\/div>\n
Step-by-step guide<\/h2>\n
You can have your new SIP trunk up and running in a few minutes – at zero fixed cost<\/a> – by following these steps:<\/p>\n
\n
Create a free account
\nSign up for a<\/span> free account here<\/a>.<\/li>\n
Get a phone number for testing
\nOn the<\/span> phone numbers page<\/a> you can select a free trial number. This allows you to test things a few days for free.\u00a0<\/span><\/li>\n
Redirect incoming calls to your SIP address
\n Configure<\/a> your free trial number to send incoming calls to the SIP address of your server (see below).<\/span><\/li>\n
Configure FreePBX
\nFollow the steps in the next section to configure your FreePBX to receive and make calls via your new SIP trunk.<\/span><\/li>\n<\/ol>\n
<\/p>\n
Your free test account comes with some free credit in your prepaid account for making some test calls. Calls are deducted at the call rates shown here. Please note that Premium gives you 40% discount on calls.<\/div>\n
<\/p>\n
<\/p>\n
Whitelist IPs for outgoing calls<\/h2>\n
To allow outbound calls, you need to get the Public IPs of your servers whitelisted.<\/p>\n
\n
Send your public IPs
\nSend your server Public IP addresses to support@sonetel.com<\/a> so that they can be whitelisted.<\/span><\/li>\n
Whitelist IPs in your Firewall
\nWhitelist Sonetel ‘s IP addresses<\/a> in your FreePBX firewall and under pjsip trunk.\u00a0<\/span><\/li>\n<\/ul>\n
<\/p>\n
Whitelist IPs for incoming calls<\/h2>\n
To allow incoming calls to reach your FreePBX you need to whitelist the IPs in FreePBX –\u00a0 that the calls (and audio) will originate from.<\/p>\n
\n
Whitelist the IPs
\nGo to Connectivity > Firewall > Networks, and whitelist all <\/span>these IP addresses<\/a> in Firewall Networks, Intrusion Detection.<\/span><\/li>\n
Check the FreePBX firewall guide
\nSee the recommended firewall settings in FreePBX<\/a>.\u00a0<\/span><\/li>\n<\/ul>\n
See the below screenshots for reference.<\/p>\n

<\/p>\n
Create a SIP trunk in FreePBX<\/h2>\n
Next, you need to configure the inbound call settings in your FreePBX to ensure that incoming calls across your SIP trunk can be answered.<\/p>\n
Create a SIP Trunk and an Inbound route for receiving calls.<\/p>\n
\n
Create PJSIP trunk<\/strong><\/span>
\nFirst Create a pjsip trunk for inbound calls using IP Based authentication. Go to Connectivity -> Trunks create a new trunk selecting \u201cAdd SIP (chan_pjsip) Trunk” type. Add below details in the trunk configuration.<\/span><\/p>\n
\n
General Settings<\/span><\/strong>\n
\n
Trunk Name: sip.sonetel.com<\/span><\/li>\n
Set outbound Caller ID: Sonetel Number<\/span><\/li>\n<\/ul>\n<\/li>\n
PJSIP-> General Settings<\/span><\/strong>\n
\n
Authentication: None<\/span><\/li>\n
Registration: None<\/span><\/li>\n
SIP server: sip.sonetel.com<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n
Submit<\/strong>
\nAfter making the changes click on Submit and apply the configuration to save the settings.<\/span><\/li>\n<\/ul>\n
See the below video for reference.<\/p>\n
