Hi all, I have a simple question regarding {}, [] and bridge application when using multiple groups/failover. For example, saying the following bridge: <action application="bridge" data="sofia/outbound/${destination_number}@ $${SBC1}|sofia/outbound/${destination_number}@$${SBC2}"/> It will try SBC1, if it fails it will try SBC2. Fine till here. If I want to add {} and [] params, how would be the correct format: 1- Once, at the beginning, and it would apply in each destination (in this example 2, but it could apply to any number of destination we add with more | separators): <action application="bridge" data="{absolute_codec_string='PCMU,PCMA'}[park_after_bridge=true,park_timeout=7]sofia/outbound/${destination_number}@ $${SBC1}|sofia/outbound/${destination_number}@$${SBC2}"/> 2- Once before each destination: <action application="bridge" data="{absolute_codec_string='PCMU,PCMA'}[park_after_bridge=true,park_timeout=7]sofia/outbound/${destination_number}@ $${SBC1}|{absolute_codec_string='PCMU,PCMA'}[park_after_bridge=true,park_timeout=7]sofia/outbound/${destination_number}@ $${SBC2}"/> 3- The {} only at the beginning, but the [] before each destination: <action application="bridge" data="{absolute_codec_string='PCMU,PCMA'}[park_after_bridge=true,park_timeout=7]sofia/outbound/${destination_number}@ $${SBC1}|[park_after_bridge=true,park_timeout=7]sofia/outbound/${destination_number}@ $${SBC2}"/> Maybe they all work, I'm just not sure what is the correct way, or if there are any best practices on this matter. Thanks, Joel.
