Phone lines and SIP

Keep your number. iCall answers it

No new number, no carrier switch. Forward your existing number, connect a carrier's SIP trunk or plug in your office PBX. Every connection is tested with you before a single real call goes through.

The phone is the hardest part of any AI rollout

  • Your number is already everywhere

    It is on business cards, on your website and on the map. Changing it means losing customers who still dial the old one.

  • Some services lock you to one carrier

    When a new system needs its own number or one specific carrier, moving in is costly and moving out is worse.

  • Your office already runs a PBX

    Extensions and routing rules are tuned and working. A new system should plug into them, not break them.

How iCall joins your line

  1. Step 1

    Choose how we connect

    Forward your existing number, add a SIP trunk or link your office PBX. We pick a ready template for your carrier.

  2. Step 2

    Test it together

    A test inbound call. If a connection fails, we find the reason together, for example: the IP address is not allowed.

  3. Step 3

    Go live on real calls

    We agree working hours and how your team is notified first, then switch on. You can turn forwarding off at any time and calls go straight back to your phone.

Four ways to connect

Every option is tested the same way before go-live.

  • Fastest

    Forward your existing number

    Turn on call forwarding at your carrier and keep the number. Callers notice no difference.

  • A SIP trunk from any carrier

    We add the trunk details (registration or IP authorisation) together. The contract stays between you and your carrier.

  • Your office PBX

    Asterisk, FreePBX and similar systems: iCall joins as a standard SIP connection. Extensions and routing stay in your PBX.

  • A new number

    No number yet? We choose the carrier and the number together, and show the telephony cost as its own line in your offer.

What we check before go-live

We switch a line to real calls only after it passes the check.

  • Line status

    The line registers and the IP address is allowed.

  • Test call

    We run a test inbound call and go live only after it passes.

  • Channels and working hours

    The number of simultaneous calls and your working hours are agreed up front.

Call → Action → Evidence

One call, from the line to the result. The example uses a fictional clinic.

  1. Call

    A patient dials the clinic's old number

    Hello, I would like to see a doctor tomorrow

    The call is forwarded from the carrier to iCall

  2. Action

    The call lands on the right line

    • The line hands the call to the assistant
    • The assistant introduces itself as an AI assistant
    • If needed, the call is transferred to an extension
  3. Evidence
