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 ? Regards, Pascal On Wed, Jul 8, 2009 at 12:25 AM, Jiri Kuthan <jiri(a)iptel.org> wrote:
