What is acTrunkProtocolType?

Configures the PSTN signaling protocol for a trunk, supporting over 20 standards including E1 ISDN, T1 CAS, and QSIG. Network operators select this based on carrier requirements and regional telecom standards to ensure interoperability. Setting to 'E1_EURO_ISDN' (value 1) enables Euro ISDN protocol compliance for European carrier trunks.
