Hello,

I want to add a SIP custom header on a SIP response generated locally (on the 408 generated when fr_inv_timeout is expired for example)

I've tried functions append_hf and append_to_reply in event_route[tm:branch-failure:XXX] or event_route [tm:local-response] without any success.

Do you have any suggestions to accomplish this ?

Regards,

Frédéric Gaisnon
