Telephony Webex by Cisco

How the calls reach her.

SIPRecommended

Security: Enterprise-grade, TLS 1.2 with SRTP
Setup: About 2 weeks
Fit: Modern, agile deployments

Fastest to deploy, cloud-ready, and nothing to lay in. This is the path for the Webex estate Children’s already runs.

Site-to-site VPN

Security: Strong encryption over a private tunnel
Setup: About 1–2 months
Fit: Hybrid networks

A tunnel between the two networks. More to configure and coordinate, and both sides own the tunnel for its lifetime.

MPLS

Security: Highest — a fully private circuit
Setup: About 3–6 months
Fit: Legacy or regulation-heavy estates

A dedicated carrier circuit. The strongest isolation available, at the cost of lead time and ongoing spend.
