here you go

(gdb) p *f
$1 = {frametype = AST_FRAME_VOICE, subclass = 8, datalen = 160, samples = 160, mallocd = 0, mallocd_hdr_len = 0, offset = 64,
 src = 0x583220 "lintoalaw", data = 0x8a3ad3c, delivery = {tv_sec = 0, tv_usec = 0}, frame_list = {next = 0x0}, has_timing_info = 0, ts = 0,
 len = 0, seqno = 0}
