[SR-Users] Add Reason Header to kamailio generated CANCEL

[Denys Pozniak]

Hello guys,

We have faced almost the same problem adding *Reason:
SIP;cause=200;text="Call completed elsewhere"* to the t_relayed CANCEL
request.
Is there an elegant solution to add this header?

PS. Switching to the stateless mode does not look pretty for us...
