I’m looking to find a way to leverage asterisk hints that could subscribe to device states located on another PBX (primarily Cisco Unified Communications Manager 9x+). I’ve tried implementing a test-example between two distinct Asterisk servers connected via registered SIP trunks, but the hints (example: 1001,hint,SIP/asterisk1/${EXTEN}) did not result in getting a successful device state despite hints/subscriptions that stay within the local context work just fine.
I am asking the community if (1) this is a possibility altogether, and if there were some examples one could provide, or (2) there was a better to way to perform device state subscriptions to other SIP-based PBXs.
