Source note · Trunks route groups and dial plans in Control Hub
Cisco states that the P-Charge-Info header cannot be included when no regular non-toll-free number is available, so the header may be absent even when support is enabled, and that PSTN providers cannot rely solely on it and must still consider the P-Asserted-Identity or Diversion header.
Checked 2026-09-15
You can’t include the P-Charge-Info header if there is no regular (non–toll-free) number available. As a result, the header may not always be present even when support is enabled.
