Among competitors, this service really stands out - they don't push their services on you (although you'll still have to set it up yourself, but the instructions are quite helpful). The prices for numbers are affordable, and the cost of calls is slightly lower than that of competitors (by 4 kopecks). The functionality of the PBX is impressive, but there's one wish - I would like a multi-level voice menu. On the plus side, there's free integration with Bitrix 24 and free call recording. However, there are also downsides: the support chat window sometimes closes, and then you have to rewrite everything, and a couple of times on weekends the number didn't work due to missed payments (it would be nice if the number was automatically renewed and money was deducted from the card without unnecessary actions).
