A dedicated phone line for customer support

Updated 2026-10-22 · By the Smart Messaging team (Smart Messaging Inc.)

Short answer: Use a real toll-free number where available, so customers can call without worrying about cost, and local numbers in other markets. Smart Messaging support lines plug into 3CX, Asterisk or FreePBX queues and IVR menus, agent softphones like Zoiper or Bria, a browser dialer, or forwarding to an on-call phone, with unlimited incoming calls and SMS.

A support line should be easy for customers to find, cheap for them to call and simple for your team to answer. Smart Messaging gives you real toll-free and local numbers that plug into the tools your agents already use.

Choosing the right kind of support number

Toll-free numbers, where available, let customers call without worrying about cost, which suits order problems, billing questions and anything urgent. Local numbers feel familiar and are often the easiest option for customers calling from mobiles.

Many teams use both: a toll-free line in their biggest market and local numbers elsewhere. Availability of each type varies by country.

Toll-free or local support number

Number type	Suits
Toll-free	Order problems, billing questions and urgent issues, since customers call without worrying about cost
Local	A familiar number, often the easiest option for customers calling from mobiles
Both	A toll-free line in your biggest market and local numbers elsewhere

Connect it to your call center

Because the number is delivered over standard SIP, you are not locked into one vendor. If you change helpdesk or PBX later, you move the credentials and keep the same published number.

Register the SIP credentials on 3CX, Asterisk or FreePBX to route calls to queues, IVR menus or ring groups.
Give agents a softphone such as Zoiper, Bria or MicroSIP on their computers, including staff working from home.
Use the browser dialer for quick call-backs without installing anything.
Forward the number to an on-call phone when the desk is closed.

Matching your business hours

Support rarely runs around the clock at a small company. With forwarding and PBX routing you can send calls to the office during the day, to an on-call colleague in the evening and to voicemail on your PBX at night.

If your team works across time zones, numbers in different countries can all land in the same queue, so whoever is online picks up.

State your hours clearly next to the number on your website and in order emails. Customers are far more patient with a line that says when it is staffed than with one that simply rings out.

Texts are part of support too

Customers sometimes reply by SMS, and many support tools send verification or notification codes. Incoming SMS appear in the Smart Messaging dashboard in real time, and you can reply using your monthly outgoing SMS allowance.

Give team leads access to the dashboard so a code sent to the support line is never stuck with one person. Outgoing texts are for individual replies to customers, not marketing blasts.

What each support number includes

There is one simple plan: unlimited incoming calls and SMS, so a busy week never costs extra on inbound; 1,000 outgoing minutes and 500 outgoing SMS per month for call-backs and replies; SIP credentials, forwarding and a browser dialer. From $1.80 per month, billed yearly ($21.60 per year). Every number also carries a 7-day replacement guarantee.

Launching your support line

Before going live, ask a colleague to call the number from a mobile and a landline, outside and inside business hours, so you can confirm that routing, forwarding and voicemail behave the way you expect.

Decide which countries you support and whether each needs toll-free or local.
Order the numbers and fund your wallet with USDT or USDC.
Add the SIP trunk details to your PBX or agents' softphones and place a test call.
Publish the number on your help center, order emails and contact page.
