searched "phon" and got 24 hits including incoming/outgoing/missed/vibrate variants, not just one generic handset glyph, that granularity is what actually saves time versus other free icon sets. left a full review too. one request since you asked: a "call recording" or "waveform" icon would be handy for anything voice/telephony related, that combo is surprisingly hard to find in most free sets.
@galdayanΒ thank you for the kind words. We have added a bunch of icons for phone https://iconsforfree.com/?q=phone liek call recording, transfer, end voicemail, noise reduction, etc. and also waveforms https://iconsforfree.com/?q=wave
