The module seems to be simply missing, according to:

After a 'guix system reconfigure' that successfully changed
/run/current-system.

I was expecting the module should have been pulled in the closure via
the encapsulating:

--8<---------------cut here---------------start------------->8---
    (with-extensions (list guile-packrat ;used by guile-ac-d-bus
                           guile-ac-d-bus
                           ;; Fibers is needed to provide the non-blocking
                           ;; variant of the 'sleep' procedure.
                           guile-fibers)
      (with-imported-modules (source-module-closure
                              '((gnu build dbus-service)
                                (gnu build jami-service)
                                (gnu build shepherd)
                                (gnu system file-systems)))
--8<---------------cut here---------------end--------------->8---

in (gnu services telephony) around line 312.

Thoughts?
