What exactly is the appropriate syntax for the value of the ac_extra_hdrs option in K3's 'tm'?
As described here, it is not very clear:
http://www.kamailio.org/docs/modules/3.0.x/modules/tm.html#ac_extra_hdrs
modparam("tm", "ac_extra_hdrs", "myfavoriteheaders-")
What does this mean? Where do I put the header name, and what is the delimeter? Is it a semicolon or colon-separated list? What if, for example, I want to pass X-Alex-Status and X-Alex-Cause in CANCELs and negative ACKs from the original INVITE? Do I use ...
modparam("tm", "ac_extra_hdrs", "X-Alex_Status;X-Alex-Cause")
If so, what is the significance of the '-' in the above example?
Thanks!
