[OpenSER-Users] 答复: how to configure to support PRACK

Hi I?aki, At first, I repied the PRACK without Route header but contian the to tag. I added the Route header after receive your opinion. But also failed. I attached my SIP message, could you please take a look them and give me some suggestion? Thank you!

PRACK is an in-dialog request, just it. I suppose that the 183 OpenSer forwards to UAC contains a Record-Route added by OpenSer in the INVITE, so the PRACK must contain a Route header and also the To tag received in the 183. Then "has_totag" and "loose_route" return true so a simple t_relay must work. Nothing special must be done, I sure it by experience.
