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.
