I have a FreePBX 16 setup with two trunks from two different providers. Both providers require the Caller ID be set as part of their authentication protocols which seems reasonable to me.
I setup an outbound route that tries one then the other and have found if I do an emergency call it is not using the caller ID from the trunk (as indeed it tells you in the documentation). Unfortunately I can’t set the emergency caller ID in the extension as it needs to change according to which trunk is used (they both have the same physical address and I want to cater for the scenario where one line is in use).
Force Trunk CID: Always use the CID defined for this trunk except if part of any EMERGENCY Route with an EMERGENCY CID defined for the extension/device.Intra-Company Routes will always trasmit an extension’s internal number and name.
So with that in mind, if you erase the “Emergency CID” from the extensions, would that not resolve the issue?
thanks for replying! Sadly not. The trunks are currently part of an Emergency Route but no Extension Emergency IDs are currently set (as I need different ones for each trunk). So it is not clear to me what ‘Force Trunk CID’ means in that scenario. I could remove the ‘Emergency Route’ tag on the route and then the Force Trunk CID could come into play?
