High-quality and inexpensive VoIP telephony without additional services. What to choose?

Question

Telephony

Good afternoon dear community!
The issue of high-quality outgoing voip-telephony is very acute in our company. What is the problem: now we use the services of the zadarma provider, this is perhaps one of the cheapest operators that provide package communication tariffs without any additional services, we easily set up sip accounts there, bought a St. Petersburg number (our main office is in Petrozavodsk and I already had a number, I needed a number for an office in St. Petersburg), everything would be fine - but the quality is just awful. Constant silence or gurgling in the handsets or headsets of managers - how many times they did not contact the support service - the problem was eliminated, but not for long. As they explained to me - since the connection is so cheap, then the channels used are not particularly wide and cheap.
In this regard, I am looking for a provider that could only provideoutgoing-incoming voip telephony, the problem is this: there are good offers for prices, for example, MTT (YouMagic) or ClickPhone, Telfin, BUT: basically everyone provides a connection with the condition of mandatory connection of services that I don’t need, like their virtual PBX (we have She is and completely satisfied).
Could you tell me from whom you can simply buy a connection (voip outgoing-incoming) without additional expenses, inexpensively (reasonably) and of high quality. The main calls go to the cities: Petrozavodsk, St. Petersburg and the region, Moscow and the region, mobile within Russia.

Answer 1

for outgoing calls, no one bothers to use several operators
with incoming calls, the problem is in the binding
, you can also look at telecomtechnology.net
though the tariffs are in the enemy currency, but as a reserve it will do

Answer 2

Didn't understand how
How are you going to use high-quality communication from another operator through Zadarma's shitty channels to Zadarma's PBX ??? How do you see yourself incoming communication from another operator to the St. Petersburg number of Zadarma ???
In 2013, they used Zadarma - the quality of calls within Russia is very low, when calling to Uzbekistan, Turkmenistan - 80% of attempts - there was no connection at all. At the end of 2013, Zadarma was banned in Belarus. There was only an incoming connection. Switched to Telfin. Have got new numbers, new automatic telephone exchange. No problem. Good business quality.

Answer 3

I can offer 1.29 rubles per minute to a mobile phone in Russia (with a volume of 15k minutes per month) and excellent quality. There are numbers for almost any city.
Although, everything is discussed! In addition to telephony, there are many interesting things. Contacts in profile.

We use FreeZvon VoIP telephony services. A very high-quality service, all virtual numbers work without a SIM card, you do not need to bother and run a telephone line. In general, we bought a virtual fax number for work, and sold the old fax machine. We now accept faxes to e-mail in a modern way. The entire office has access to the box and views the fax at any convenient time.

Answer 6

If you don’t need overloaded functions, then it’s worth testing the WestCall virtual connection (westvirt.ru), especially since testing is free for 2 weeks, since this provider offers a PBX operation scheme based on the type of activity, number of staff and branches, and as well as the number of calls. In addition, it is possible to design the scheme at your discretion.
