The user agent in the Debian package does not deviate from Upstream.
However, the version string in the Debian package includes a '~'
character that is not included in Upstream.

sip.conf already includes an example line (remmed out):

;useragent=Asterisk PBX         ; Allows you to change the user agent string
                                ; The default user agent string also contains the Asterisk
                                ; version. If you don't want to expose this, change the
                                ; useragent string.

Likewise in pjsip.conf (for Asterisk >= 13):

;user_agent=Asterisk PBX SVN-branch-12-r404375  ; Value used in User Agent
                                                ; header for SIP requests and
                                                ; Server header for SIP
                                                ; responses (default: "Asterisk
                                                ; PBX SVN-branch-12-r404375")

I see indeed that this example configuration file needs fixing. The
default value uses the current version, of course.

So I don't see anything that needs fixing here. Apart from the minor
issue with the text of the description of the pjsip.conf option
"user_agent". But that is for upstream.
