• The TAC procedure for collecting Local Gateway call traces enables debug ccsip messages and debug voice ccapi inout, logs to a large debug-level buffer, and turns off console and monitor logging and logging rate and queue limits. in context
• With premises-based PSTN, if the PSTN provider's post-dial delay exceeds 12 seconds, Webex Calling automatically cancels the call. in context
• To get the PDD limit extended beyond 12 seconds, TAC advises opening a Webex Calling support case with Local Gateway traces attached. in context
