If true, and the conversation was part of their ad buy, there could be a violation here. From the FCC Rules Sec. 73.1212 Sponsorship identification; list retention; related requirements.
(a) When a broadcast station transmits any matter for which money,
service, or other valuable consideration is either directly or
indirectly paid or promised to, or charged or accepted by such station,
the station, at the time of the broadcast, shall announce:
(1) That such matter is sponsored, paid for, or furnished, either in
whole or in part, and
(2) By whom or on whose behalf such consideration was supplied:
Provided, however, That ``service or other valuable consideration''
shall not include any service or property furnished either without or at
a nominal charge for use on, or in connection with, a broadcast unless
it is so furnished in consideration for an identification of any person,
product, service, trademark, or brand name beyond an identification
reasonably related to the use of such service or property on the
broadcast.
(i) For the purposes of this section, the term ``sponsored'' shall
be deemed to have the same meaning as ``paid for.''
(edited some non-relevant sections)
(e) The announcement required by this section shall, in addition to
stating the fact that the broadcast matter was sponsored, paid for or
furnished, fully and fairly disclose the true identity of the person or
persons, or corporation, committee, association or other unincorporated
group, or other entity by whom or on whose behalf such payment is made
or promised, or from whom or on whose behalf such services or other
valuable consideration is received, or by whom the material or services
referred to in paragraph (d) of this section are furnished. Where an
agent or other person or entity contracts or otherwise makes
arrangements with a station on behalf of another, and such fact is known
or by the exercise of reasonable diligence, as specified in paragraph
(b) of this section, could be known to the station, the announcement
shall disclose the identity of the person or persons or entity on whose
behalf such agent is acting instead of the name of such agent.
(more edits)
(f) In the case of broadcast matter advertising commercial products
or services, an announcement stating the sponsor's corporate or trade
name, or the name of the sponsor's product, when it is clear that the
mention of the name of the product constitutes a sponsorship
identification, shall be deemed sufficient for the purpose of this
section and only one such announcement need be made at any time during the course of the broadcast.
