Note
  • SBC uses iceFull to support faster completion on the ICE exchange as the two end points locks down on the first accessible connection path attempted.
  • SBC uses iceWebrtc to allow selection of the optimum connection path, for example, Host vs TURN address.

Assigning SMM Profiles to Assigning SMM Profiles to Trunk Group

The SMM profile is applied to the Trunk Group as shown below:

Other Configuration

Code Block
languagenone
set addressContext default zone ZONE_IAD sipTrunkGroup TG_SIPART_IAD services natTraversal mediaNat disabled
set profiles media packetServiceProfile PSP_IAD rtcpOptions rtcp enable
Note

The STUN handling for media NAT and ICE are mutually exclusive. Therefore, mediaNAT is disabled when ICE is used.

For DTLS, an association is created for both RTP and RTCP. The RTCP control must be enabled for RTCP packets to flow.
