How UnlimCall works

Three steps to unlimited calling. No platform migration. No hidden fees. No bullshit.

Step 1

Pick your countries.

On unlimcall.com/signup, tell us:

Your company name and contact email
Which countries you want to call (we have 33)
How many agents (minimum 5–10 depending on the country)
Pay your first month via credit card, SEPA, or USDT

Time: 5 minutes.

Step 2

We provision your trunk.

Behind the scenes, we:

Provision your SIP credentials on our carrier-grade backend
Assign you a clean rotating pool of local CLIs in each country you subscribed to
Configure routing through our regional edge POP nearest your operations
Sign your North American calls with STIR/SHAKEN
Hand-test the trunk with our NOC team

Time: 5–7 business days for standard markets, 7–10 for markets requiring local docs.

Step 3

Configure your VICIdial / Asterisk / FreeSWITCH.

You receive a clear configuration guide for your dialer. Drop our SIP credentials in. Make a test call. Verify everything works. Start your campaign.

Time: 30 minutes for an experienced VICIdial admin.

How calls flow

   Your VICIdial  ──→  Regional edge POP  ──→  Our backend  ──→  Carrier  ──→  Recipient
   (Anywhere)         (Frankfurt / Ashburn         (Routing,       (Local
                       / Sydney / etc.)            CLI pool,        carrier
                                                    CDR, billing)    in country)

Why multi-region matters

Your SIP signaling and media don’t have to cross the Atlantic to get to us. We have edge POPs in Europe, North America, Australia, and more — your calls hit the nearest one for low latency, then we route intelligently to the carrier that connects to your destination.

Why direct routing matters

We’re not reselling someone else’s reselling. Direct origin-based routing means our cost basis is well below retail per-minute rates — which is why we can offer flat-fee unlimited and still profit.

What setup looks like for popular dialers

VICIdial

1. Add carrier in admin GUI
2. Carrier Description: UnlimCall
3. Registration string: register => unl_USERNAME:PASSWORD@sip-eu.unlimcall.com
4. Account entry:
   [unlimcall]
   type=peer
   host=sip-eu.unlimcall.com
   username=unl_USERNAME
   secret=PASSWORD
   ...
5. Test call → verify CLI presents correctly

Asterisk (chan_pjsip)

[unlimcall]
type=endpoint
context=from-trunk
disallow=all
allow=alaw
allow=ulaw
auth=unlimcall_auth
aors=unlimcall_aor
outbound_auth=unlimcall_auth

[unlimcall_auth]
type=auth
auth_type=userpass
username=unl_USERNAME
password=PASSWORD

[unlimcall_aor]
type=aor
contact=sip:sip-eu.unlimcall.com:5060

FreeSWITCH

<gateway name="unlimcall">
  <param name="username" value="unl_USERNAME"/>
  <param name="password" value="PASSWORD"/>
  <param name="proxy" value="sip-eu.unlimcall.com"/>

Setup FAQ

How long until I’m live?: 5–7 business days for standard markets. 7–10 for markets requiring local docs (some EU countries). Premium tier with full KYC: 7–14 days.
Do I need new hardware?: No. UnlimCall is pure SIP — works with whatever you have. If you can register a SIP softphone, you can use UnlimCall.
Can I migrate my existing numbers?: Most countries support number portability. We handle the porting workflow on your behalf — typically 5–14 business days. Contact us for specifics per country.
What about codecs?: We support G.711 (alaw/ulaw), G.722 wideband, and OPUS. G.729 is not supported (licensing). Most VICIdial setups use alaw — works perfectly with us.
Do I need to open firewall ports?: For outbound: SIP/UDP 5060 to our edge POPs (or 5061 for TLS). RTP/UDP range typically 10000–60000. We document exact ranges per region.
What if my IP changes?: Tell us — we update your IP allowlist within minutes. Your devices keep working.
Can I have multi-country desks?: Yes. Subscribe to multiple countries simultaneously. We give you separate SIP credentials per region for clean isolation, plus a 5% multi-country bundle discount.
