If you’ve decided to work with oki-toki — you need telephony. In our service, we have queue routing, dialers, scripts, reports, but without a SIP number, the system simply won’t be able to receive and make calls.
A SIP number is a regular city or mobile number that works via the internet. It connects to oki-toki in a matter of minutes, and from then on all the traffic goes through the system.
The question usually sounds like this: which provider should I choose in Kazakhstan to avoid problems? We’ll help to figure it out. Below we’ve gathered communication operators offering SIP services in Kazakhstan.
*All material does not have a promotional intent, the information is obtained from official websites and based on the experience of our clients. Rates and conditions should be verified with the operator. oki-toki is not their representative.
What’s important to consider when choosing a SIP provider
Before looking at the list of companies, you need to understand that you’re choosing not just a number, but infrastructure.
The provider determines not just the “SIP number”, but how your entire call center will work.
Specifically, it defines:
- whether the client’s number (Caller ID) is transmitted correctly;
- whether the line withstands simultaneous calls and peak loads;
- whether dialers are limited during mass campaigns;
- how quickly additional channels can be connected as the team grows;
- whether there are any delays, interruptions, or problems with sound quality;
- how quickly technical support responds in case of failures;
- whether routing requirements are met and certain directions are not blocked.
The SIP provider is the foundation of the entire voice infrastructure. If it works stably, you won’t even notice it. If not — problems become visible immediately: in reports, in dialing dips, and in the agents’ nerves.
Sometimes everything is fine at the connection stage, but surprises start when the load grows. Therefore, the choice should be made consciously.

Mistakes often made when choosing
Only looking at the connection price
Low start-up cost is not always the beneficial option.
Sometimes the connection is inexpensive, but:
- the subscription fee is above market;
- each additional channel is charged separately and expensively;
- there is a charge for activating outbound directions;
- hidden traffic limits apply.
In the end, the savings at the start turn into constant additional expenses.
Not specifying dialer restrictions
If massive outbound traffic is planned, this point is critical.
Some providers:
- limit the number of simultaneous outbound calls;
- limit the rate of making new calls (Call Per Sec);
- block the number with a sudden increase in activity;
- require separate approval for dialers;
- filter traffic without warning.
As a result, dialing can stop at the most active moment of the campaign.
Not checking the transmission of the client’s number (Caller ID)
It seems obvious that the caller’s number should be transmitted correctly.
But in practice, situations occur when:
- the number is displayed in the wrong format;
- a technical number is transmitted instead of the real one;
- CRM does not recognize the incoming contact;
- outgoing Caller ID does not pass with communication operators.
This affects analytics, reports, and agents’ work.
Not testing the load
At the start, everything works stably — one agent, a few calls. But when 10–20 employees are connected, there can be delays in connection, degradation of sound quality, interruptions, missed calls, etc.
It’s important to test operation under real load, at least during peak hours.
Not specifying technical details
Another frequent point — not finding out in advance:
- whether SIP registration is supported or only SIP trunk;
- are there restrictions on IP addresses;
- is a static IP required;
- how quickly can new channels be added.
These nuances become important when scaling.
What happens in the end
The number is connected, employees are working, but a month later complaints begin: dialing drops, agents hear delays, static, and you have to change the provider already in the process of work.
It’s better to connect a test number in advance, check incoming and outgoing, run the load and clarify all restrictions. Telephony is the base of the entire system. If it works stably, the rest of the call center will also work calmly.
Recommendations from oki-toki
Don’t rush to connect several numbers at once. Start with a single test number — that’s enough to understand how the provider works under real conditions.
What’s worth checking:
- how incoming calls are processed;
- whether outgoing calls are stable;
- are there any restrictions on dialing;
- can the line handle the load during peak hours.
It’s important to look not only at whether it “works / doesn’t work”, but at the system’s behavior under load: are there any delays in connection, disconnections, blockages of outgoing calls during mass campaigns.
If the provider smoothly handles traffic and doesn’t introduce unexpected restrictions — you can scale further.
Telephony is the foundation of the entire call center’s operation. If the connection is unstable, problems begin to appear in reports, in dialing, and in agents’ work. And no scripts or CRM can compensate for this.
