I am not at all trying to compare asterisk to kamailio, just trying to find out what each is intended to do, in words and concepts that are familiar to me.
In that case, I invite you to think of Kamailio as a "call router."
So this means, that if I put kamailio as a frontend to my current asterisk setup, and most calls run outside asterisk, that the operator will not be able to for example break into an already existing conversation?
If they run outside of Asterisk in both the signaling and media respects, that is correct.
Or pull two established channels away from each other and forcibly redirect them to a conference box?
Correct.
Hm, now I am getting a bit worried. Scaling up my asterisk setup using OpenSER will definitely not be as easy as I thought...
So what parts can be done by openser itself? Can it do:
- Attended transfer? - Call Pickup? Directed? - Barge In (no, you already said so) - Call recording (mid call) - Listening-in (Training)
Also, asterisk has long had serious problems with showing callerid/connected party after attended transfer, blind forward or call pickup. Does OpenSER have those problems too? Does it support P-Asserted-Id or Connected Party?
If a lot of calls need one of the above features, then using kamailio does not scale up my asterisk-based PBX too much, does it?
Thanks for your answers.
