Use the generateCallIdWithDialogTransparency to natively generate the callID call ID even when dialog transparency is enabled. The CallID Call ID is generated on the egress side.

Multiexcerpt
MultiExcerptNameGenerateCallIdWithDialogTransparency Overview

The SBC sends out multiple 18x messages (when using the Dialog Transparency feature) even when the ingress leg does not support 100rel/PRACK. The SBC processes all 18x messages with SDP answers (with different codecs) received at the egress leg, and then sends ingress SDP answers in all of the 18x messages at the ingress leg.

Additionally, this flag is added at the Zone level for the SBC to natively generate the Call ID on the egress leg when the Dialog Transparency is enabled.

Info
titleNote

To use this feature, you must enable the following flags:

  • Transcode Free Transparency – on both legs
  • Dialog Transparency – on both legs
  • Downstream Forking Support – on the egress leg (The SBC supports up to 10 forked calls)


Info
titleNote

The SBC transparently relays the PEM header to the other leg only when the P Early Media transparency flag is enabled.
