Carrier configuration

Add VoIP Kart as a Vicidial carrier

In the admin, go to Admin, Carriers, Add a new carrier. Replace YOUR_SIP_HOST with the endpoint from your welcome email. Treat these as starting points and adjust them for your server version and security policy.

Globals string

VOIPKART = SIP/voipkart

The variable name is used in the dialplan entry.

Dialplan entry

Campaign settings

Starting points for your campaigns

Best values depend on your list quality, agents and market. Begin conservatively, then adjust using your answer rate and drop rate reports.

Vicidial setting	Suggested starting point
Dial method	An adaptive method such as ADAPT_TAPERED or ADAPT_AVERAGE
Auto dial level	Start low, around 1.5, and raise gradually as agents fill
Adaptive dropped percentage limit	At or below the legal limit for the market you dial
Dial timeout	Around 26 to 30 seconds
Dial prefix	Must match the prefix in your carrier dialplan entry
Campaign caller ID	A valid number you own, that can be called back

Troubleshooting

If calls do not connect

403 or no response

Your server IP is probably not on the allow-list. Send us your current public IP.

Calls fail instantly

Check the dial prefix, the dialplan pattern and that the number is in E.164 format.

One-way or no audio

Check NAT, firewall and RTP port range, and that both sides share a codec.

FAQ

Vicidial questions

Does VoIP Kart work with Vicidial?

Yes. Vicidial is built on Asterisk and connects to any standards-based SIP carrier. Add VoIP Kart as a carrier in the Vicidial admin and point your campaigns at it.

Which codec should I use with Vicidial?

G.711 (ulaw or alaw) works out of the box on a standard Vicidial install. G.729 saves bandwidth but needs a codec licensed and installed on your dialer servers.

How do I get my IP allow-listed?

Send us your dialer server public IP addresses with your test account request. Each server that places calls needs to be allow-listed.

What drop rate should I use?

Set the adaptive drop limit at or below the legal limit for each market you dial. See our compliance page for the key rules by country.

Can I run several Vicidial servers?

Yes. Allow-list each server IP and we can set channel and call-rate limits to match your cluster capacity.
