We're considering buying some Yealink phones for our Skype for Business Online / "Microsoft Phone System" deployment:

Does the SILK codec work for standard calls from T48G -> remote PSTN users?

Like, if we're using Skype for Business Online / Cloud Voice, and we call from a T48G to a random US phone number, will that use SILK?

HI Steven,

For the SFB T48G, we can't support SILK codec, but the SFB T4S can support SILK codec.

In T4S phones, you can enable SILK codec via web interface->account->codec.
