• For certificate-based trunking the colocation configuration differs only in Local Gateway trunk and tenant parts: a TLS profile with cn-san validate bidirectional, a SIP OPTIONS keepalive profile over TLS, and a DNS session target for the Webex SIP connect address. in context
• Colocation applies only to Cisco IOS gateways: customers with a third-party Local Gateway must deploy the Survivability Gateway separately, and colocation does not apply to a partner-deployed Local Gateway shared across multiple customers. in context
• In the colocation configuration an emergency e164-pattern-map (300, pattern 911 in the example) is used so the emergency dial-peers match only calls from endpoints registered directly to the Survivability Gateway in Survivability mode. in context
• On a colocated gateway, High Availability and config validation are not supported for the Local Gateway. in context
• In the colocation configuration, outbound dial-peer preference 0 (default) routes to locally registered endpoints, preference 2 to the Webex Calling trunk and preference 3 to the PSTN trunk, with dial-peer hunt 2 selecting by preference. in context
• A colocated gateway must be provisioned in Control Hub as a Survivability Gateway service; a gateway already provisioned as a Local Gateway must be unassigned and then reassigned as Survivability Gateway. in context
• On a colocated gateway the total registrations supported by the platform is the sum of phone and trunk registrations. in context
• Colocating Local Gateway and Survivability Gateway services on one Cisco IOS gateway requires Cisco IOS XE Dublin 17.12.3 or later. in context
