Which SIP-E1 gateway to choose?

Question

SIP

Greetings!
In the new office, it was necessary to set up IP-telephony. The provider provides an E1 stream. If I figured out asterisk, then there is still a problem with the VoIP gateway. There will be about 10-15 lines in total (well, if you take it with a large margin).
Advise from personal experience any gateway, preferably, which could be mounted in a rack. I myself looked at the Digium G100, but I don’t need another Asterisk, and, it seems to me, the price of the E1 is very high there (50 tr is a bit too much, in my opinion).
Thank you!
