Hi,
Some comments on Yate.
Yate works well as a B2BUA. It is very performant and stable. It can bypass media
dynamically.
The main beauty of Yate is how it processes calls internally. Yate represents calls
internally as messages with parameters (caller, callee, codecs …) . While the call passes
from the incoming to the outgoing call leg the message parameters can be manipulated by
different yate modules. In turn, message parameters can trigger yate modules for some
actions, e.g. start a sip call.
The Yate internal messaging allows to build with little code complex call logic. E.g a
mysql query result can be used directly for routing. E,g, you can build a switch just with
a couple of mysql procedures.
Cheers
Gerry

Hello,
just for the records:
You can also bypass media with FreeSWITCH if you want. The overall handling of many
parallel calls is still not so high like in SEMS.

<https://freeswitch.org/confluence/display/FREESWITCH/Proxy+Media>
This is also possible on a per Call base.
And you can use different profiles as well in FreeSWITCH.
Asterisk Experts will have more knowledge what is possible there, and maybe someone told
us whats going on with Yate.
Kind regards
Karsten

Hello there,
According to ,https://lists.kamailio.org/pipermail/sr-users/2016-March/092058.html
<https://lists.kamailio.org/pipermail/sr-users/2016-March/092058.html>, which talked
about B2BUA (just signalling) in Kamailio.
As i have experienced working with SEMS, freeswitch and Kamailio while using B2BUA
feature, Each of them have pros and cons:
1- The sems is a light sip engine server with several applications (like as sbc) for
using b2bua. All incoming and outgoing calls could go to sems server for doing b2bua like
this:
Incoming<=======>Kamailio<========>Sems<========>Kamailio<=======>outgoing
2- In sems, you could disable rtp realying. It forces sems to work just as b2bua without
anchoring RTP
3- Easy to use different active profiles in routing.
