M4 Switch Manual



Is it M2 or M4?

M2 is an old version of M4. M2 was based on Freeswitch which was slow and buggy. We reworked the system to use Kamailio/SEMS/RTPEngine, improved its performance many times, and named it M4.

In many places in the documentation, you will find M2 references, we will change this with time, but currently, it means that this functionality came from M2 and is still applicable to M4.



Differences from MOR

Below you can see the most important differences between M4 and MOR:

  • M4 Switch is designed for wholesales business (Class 4 Switch), MOR - for retail (SIP Trunking, Calling Cards, Call Back, Call Shop, Resellers, etc) and is not optimized for wholesale.
  • M4 Switch uses Kamailio/SEMS/RTPEngine as a SIP engine which allows having twice bigger performance compared with MOR which is based on Asterisk.
  • M4 Switch logical structure allows to manage wholesale business very easy. Accomplishing the same tasks with MOR is more complicated and you need to dedicate much more time.



Why should I use it?

M4 Switch gives never-seen-before flexibility when managing traffic transit.
