[OpenSIPS-Users] QoS/ToS Opensips

[Jeff Pyle]

Peter,

Additionally, and slightly off list topic… If there's a standard, I would suspect it's AF31 for SIP (0x68) and EF for RTP (0xb8).  I've seen several gateway manufacturers' equipment use these values by default.  CS6 and CS7 are generally reserved for network operations only.  I haven't done any research to see if there is anything official to this.

Peter,

See the "tos" option to set SIP ToS values:
  http://www.opensips.org/Resources/DocsCoreFcn16#toc89

A CS5 value would be tos=0xa0 I believe.  EF may be a more compatible value (0xb8), and it will also be detected as CS5.  Here's a great QoS cheatsheet:

Opensips does not handle RTP, so there is no relevant setting.

Is there a way to set these values for Opensips?
I would like to use CS5 for signaling and CS6 for RTP/Voice.
