[SR-Users] Build version in custom server_header

[Asgaroth]

Hi All,

Is it possible to have the build/git version added in a custom
server_header/useragent_header? For example, my kamailio version is:

version: kamailio 3.2.0 (i386/linux) 94d3b8

if I had the following config options:

server_header="Server: Proxy"
useragent_header="User-Agent: Proxy"

Is it possible to do something like:

server_header="Server: Proxy ($buildver)"
useragent_header="User-Agent: Proxy ($buildver)"

Where "$buildver" is the build/git release (94d3b8)? I'm looking at the
core cookbook but I dont see anything that jumps out at me, is there a
variable that can do this?

Thanks
