Hi, I am using Asteriks 13 with pjsip 2.3.I am trying to transparently pass ISUP data arriving with the INVITE to another destination after I perform Dial(PJSIP/..) to another provider.The multipart body is removed once I execute the next Dial().Ideally, it would somehow parse incoming message and store the isup data in a variable, and then attach it back - is this doable?Alternatively, can the transparent isup forwarding be enabled? I have found some documentation on?pjsip_multipart_part and assume that it is supported, but not sure how to use it. Thanks,Andrei -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20150713/be79aeb3/attachment.html>
