[Freeswitch-users] Escape variable content when used as a field in a condition

Hello all, I'm trying to compare 2 variables in a condition, something like <condition field="${sip_from_user}" expression="^${some_other_phone_number}$" inline="true"> But it looks like FS expands the variable, and does the comparison. The problem with this is, those 2 phone numbers are in e.164, i.e.: sip_from_user = +18885551212 some_other_phone_number = +18005551212 and so the condition ends up being: <condition field="+18885551212" expression="^+18005551212$" inline="true"> which of course won't work.... Is there any way of escaping the variables automatically when comparing? I haven't found a way. Thanks! David Villasmil email: david.villasmil.work@gmail.com phone: +34669448337
