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
