Vicidial SIP Trunk with Twilio - asterisk

Question

I need a step by step guide on configuring Twilio Elastic SIP Trunk on my Vicidial Server. I've been working it out for days now. Still can't make an outbound call. My account on twilio is still a trial account. thank you guys. :(

Answer 1

From vicidial admin panel, go to Admin >> Carriers
Add a new carrier named "myname"
**Replace "myname" with whatever you like but keep it consistent throughout the config. Anywhere you see "myname" replace it with the same value.
In the account entry section use this template:
Account Entry:
[myname]
type=peer
secret=mypassword ;if you created a Credentials list in Twilio the password goes here
username=myuser ;the Credentials username goes here
host=mytrunkname.pstn.twilio.com ;in Twilio this is your Termination SIP URI that you created under Elastic SIP Trunk settings
dtmfmode=rfc2833
canreinvite=no
disallow=all
allow=ulaw
insecure=port,invite
fromuser=[phone] ;the phone number associated with your trunk goes here
fromdomain=mytrunkname.pstn.twilio.com
Global String: DIAL9TRUNK = SIP/myname
Dialplan Entry:
exten => _91NXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _91NXXNXXXXXX,n,Dial(${DIAL9TRUNK}/+1${EXTEN:2},,To)
exten => _91NXXNXXXXXX,n,Hangup
exten => _9NXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _9NXXNXXXXXX,n,Dial(${DIAL9TRUNK}/+1${EXTEN:1},,tTo)
exten => _9NXXNXXXXXX,n,Hangup
That should activate outbound calling prefixed with the number 9. Meaning, dial 9 and then the number you want to dial as usual. You might want to remove all of my comments in the settings just to be safe. If you need any more help post back with your current config and I'll try to respond quickly.
Cheers!

Answer 2

The above answer is several years old, and I get emails asking how to add Twilio to Vicidial quite frequently. The problem is almost always with how you configure your Twilio account. I have to admit I have found the process fairly painful.
You going to need a unique trunk name for Twilio. I recommend you head to random.org and just use a random string. Copy one and paste it into a note.
You need to use a Twilio product called "Elastic SIP Trunking". Here's what you fill in when you create your new Twilio trunk:
Trunk Name: Vicidial
Call Recording: No
Secure Trunking: Disabled
Termination URI: [that random string from random.org].pstn.twilio.com
IP Access Control Lists: (add every public IP address of your Vicidial cluster that needs to dial)
Credential Lists: (here's what people tend to mess up in my experience; make sure these are set with both username and password - I'd copy and past them into a note for reference when trunking Vicidial)
Origination SIP URI: (add the public IP address of one server of your Vicidial cluster; I tend you pick the server that's set as the voicemail server)
Priority: 10
Weight: 10
Log into your Administration interface of your Vicidial system and head to Carriers (Administration → Admin → Carriers)
Click "Add A New Carrier". It's in the grey bar across the top.
Carrier ID: Twilio
Carrier Name: Elastic SIP Trunk
Carrier Description: (I leave that blank)
Registration String: (leave that blank)
Account Entry:
[twilio]
disallow=all
allow=ulaw
type=friend
secret=(password you created in "Credential Lists")
username=(user name you created in "Credential Lists")
host=(the value used in "Termination URI", e.g. wkR9PaMPvk9h.pstn.twilio.com)
dtmfmode=rfc2833
context=trunk-inbound
Globals String:
TWILIO = SIP/twilio
Dialplan Entry:
exten => _91XXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _91XXXNXXXXXX,2,Dial(${TWILIO}/${EXTEN:1},,To)
exten => _91XXXNXXXXXX,3,Hangup
exten => _9XXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _9XXXNXXXXXX,2,Dial(${TWILIO}/1${EXTEN:1},,To)
exten => _9XXXNXXXXXX,3,Hangup
exten => _1XXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _1XXXNXXXXXX,2,Dial(${TWILIO}/${EXTEN},,To)
exten => _1XXXNXXXXXX,3,Hangup
exten => _XXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _XXXNXXXXXX,2,Dial(${TWILIO}/1${EXTEN},,To)
exten => _XXXNXXXXXX,3,Hangup
Submit and ensure the carrier is saved as Active "Y" (you'll have to submit a second time). Wait a minute or two and you should be able to send calls to Twilio. If there's a problem, double and triple check your outbound Caller ID setting as Twilio will block calls if that's not set up perfectly.
