This was asked on the mailing list earlier in the day yesterday. I’m presuming you only just subscribed. See this topic on the archive for info - http://lists.sip-router.org/pipermail/sr-users/2016-June/093348.html Phil From: sr-users [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of Marcelo Bonin Sent: 14 June 2016 16:14 To: sr-users(a)lists.sip-router.org Subject: [SR-Users] Kamailio + ToS Hello, I need to know what are the available parameters to set ToS on Kamailio. I couldn't found much information about that, only this https://www.kamailio.org/wiki/cookbooks/4.0.x/core#tos but there is no reference for the available parameters. Thanks, Marcelo.
