[OpenSIPS-Users] feasablity / interest in a feature request.

[Răzvan Crainea]

Hi Johan!

Just as Ben indicated, you should get two HEP packages per call the 
inbound, which is the message unchanged, and the outbound, which is the 
message sent over the network. Basically you should get both messages - 
are you getting only one? Or you're getting two, but duplicates?

Best regards,
