Sorry Jiri, but I disagree with you : if I understood well kamailio is still
maintained as a product and will see future evolutions. And I'm pretty sure
I will get some new issues to solve if we switch to sip-router. I need some
time before doing this.

Thanks for the suggestion Jiri. So far I have
been monitoring sr and I
know that the TCP async implementation might resolve some problems we're
facing with kamailio.
But I'm a bit conservative and I want to do several verifications of sr
before doing the "switch". So for now we stick to kamailio.
Does this TCP supervisor process priority sounds familiar to you for
tuning kamailio ?
not really -- I sort of think that studying tuning of something what is
overdue
for an update may cost you lot of time and bring less results.
