What must be different in bridged systems for outgoing calls to function correctly?

For outgoing calls to function correctly in bridged systems, the numbering plan must be properly configured and distinct. In a bridged scenario, different systems may be using their own dialing formats or country-specific numbering schemes. A consistent numbering plan ensures that when a call is initiated, the call is routed correctly across different systems or locations.

Properly aligning the numbering plans allows for seamless communication across various platforms, thus ensuring that users can make outgoing calls without encountering mismatched dialing formats that may lead to call failures. If the numbering plans do not align, calls may be incorrectly routed or fail altogether, leading to poor user experience and operational disruption.

In contrast, the routing table, SIP settings, and network protocols do play significant roles in call processing and establishing connections but do not specifically address the critical element of how numbers are formatted and recognized between different systems. This makes the numbering plan a key focus in ensuring outgoing calls are processed accurately in a bridged environment.
