Delete a customized header

Hello,

 

For a traffic case I need to save the incoming VIA header and insert it on the outgoing side as second VIA.

In fact all is working fine but for some reason the customized header I use to store the VIA header, appears also in the outgoing invite. I tried to add a delete rule but no go.

As I'm quite new in the HMR world I'm open for maybe a better solution, if there is, to save and add the VIA header.

 

Thanks in advance.

 

Incoming HMR:

header-rule
                name                           saveVIAcarrier
                header-name                    Via
                action                         store
                comparison-type                pattern-rule
                msg-type                       any
