[cisco-voip] Expressway Design for new startup

[Ki Wi]

Hi James,
you are right regarding the phone registration on Spark directly. However,
for the voice gateway connectivity for voice countries, looks like we will
have to go via Hybrid method. :(

If that's the case + customer have MPLS today. I will prefer to have the
voice traffic over MPLS. At least we can tell them that when using
deskphone, quality is guarantee.

Regards,
Ki Wi
