de-ring was not in the option list.
If multiple devices are registered with the same extension, only on device was ringing. (And this was not the device in front of you :) )
The Call UUID was 'duplicated'
The fix is to remove the origination_uuid. Then all devices rings simultaniously.
Previously, if a bridge statement was written with prepended variables to be passed, the gateway name would not be parsed and replaced. Additionally, if multiple bridges were used in failover in a single bridge statement separated by a pipe, only the first would be parsed and replaced.
I noticed this after upgrade to FreeSWITCH 1.8.5 (from 1.6.20) which changed failover behavior with multiple separate bridge statements. When network returns 486 BUSY, it will proceed to second bridge statement, initiating a second call. To allow failover and not have this behavior, you must write a single statement and separate your failover bridges with a pipe, this change allows the UI to show all gateway names on the line once saved.
Examples:
{fax_use_ecm=on}sofia/gateway/99b1234c-667c-4b31-9d2f-31d4f396abfa/$1
=> {fax_use_ecm=on}sofia/gateway/Gateway_Name/$1
sofia/gateway/0e70e123-00fd-4f0c-b525-bc7f6283cfa1/$1|sofia/gateway/99b1234c-667c-4b31-9d2f-31d4f396abfa/1$1
