🎯Advantages of IP telephony compared to GSM gateways

The use of GSM gateways often seems like an attractive idea due to the possibility of connecting multiple SIM cards with favorable tariffs. However, these savings are minimal and the risks to your business are significant.

Disadvantages of GSM gateways:

1. Low stability and quality of communication. GSM gateways create an additional load on your network, which can lead to problems with call speed and quality. Many users complain about call quality and call recording.

2. High support costs. To ensure reliable operation of the GSM gateway, you may need a separate Internet line and additional resources for system administration, which will increase your costs.

3. Risk of losing customers. GSM gateways have a limited number of channels for calls. This means that concurrent calls may not be routed to your system, resulting in the loss of customer calls.

4. It is almost impossible to find a good gateway (high-quality, durable, with updated and secure software) because they are not legal everywhere (or, more precisely, almost everywhere they are illegal). One solution is not to buy a weak gateway yourself, but to rent good gateways from a contractor. But then your gateway will be in a place where hundreds, thousands of SIM cards work simultaneously. And all of them interfere with one signal and can put down mobile communications. Just like when you try to call someone at 23:59 on 31 December. The towers simply cannot cope with the high load.

   At first glance, using GSM gateways may seem like a cheaper option than IP telephony. Let's take a closer look at the numbers using the example of 5 voice lines:

	Kyivstar (IP number)	Binotel (GSM gateway)
Tariff	SIP Simple 50	Kyivstar ‘Business UA.Meta’
One-time connection cost	1.2 UAH * 5 voice sessions = 6 UAH	-
Subscription fee per month	50 UAH * 5 voice sessions = 250 UAH	● Subscription fee for the package: 300 UAH ● Subscription fee for the gateway: 220 UAH ● Multichannel: 5 × 150 UAH = 750 UAH
Included in the tariff for using the services for	50 UAH	unlimited to Kyivstar and 300 minutes to other mobile numbers and landlines
Cost of outgoing calls (incoming calls are free)	● 300 minutes to other mobile networks and landlines: 300 minutes × 0.25 UAH = 75 UAH ● 1000 minutes to Kyivstar: 1000 minutes × 0.10 UAH = 100 UAH	-
Total	381 UAH	1270 UAH

Instead, the transition to IP telephony will ensure:

• Stable telephony operation with availability up to 99.9% of the time.

• High sound quality comparable to Viber or Telegram calls.

• The ability to easily scale the number of channels without additional costs for SIM cards.

This solution will not only help your business avoid potential telephony problems, but also create conditions for further growth.
