[Freeswitch-users] SIP header on only one fork of a bridge

Hello list, I would like to bridge a call to multiple SIP endpoints, but add different headers to each. I'm not entirely sure how to do this. I have no problem exporting a SIP header that does what I want for one destination, but I'm not sure how to set it for two. My application is that I want two IP phones to ring - one with the internal ring-ring splash, the others with a group-answer (single ring, then lamp flash only), for administrative assistants, etc. How do I export different variables to each branch? Thanks! -Tim
