http://pastebin.freeswitch.org/9365 I do not know what I am doing wrong. I am trying to set the effective_caller_id_name and _number depending on the originating extension. I tried: <condition field=${caller_id_number}$ expression="^100[09]$" break="on-true"> and <condition field=${Caller-ID-Name}$ expression="^100[09]$" break="on-true"> and <condition field=${sip_from_user}$ expression="^100[09]$" break="on-true"> But each got substituted with the name of the extension in the log: Dialplan: sofia/internal/1000@192.168.10.29 Regex (FAIL) [Long Distance - flowroute] () =~ /^100[09]$/ break=on-true where the extension looks like: <extension name="Long Distance - flowroute"> Info from the log shows variable_sip_from_user: [1000] Caller-Caller-ID-Number: [1000] Can anyone help? Thanks, Lars
