[Freeswitch-users] Convert to e.164

[ljjimenez at gmail.com]

Hello list, I have a provider who needs to receive the call prefixed with a "+" in the "From" and "To" headers, is there any dial plan function for this or how is the best practice to modify the "From" and "To" headers to prefix the + ?

Thanks in advance
