You ask a tough Q in very simple words ;-)

Since you mention managed IPT, hence I suppose Cisco CallManager (CCM) or CallManager Express (CME) based solutions will be the core of such a managed service. These products allows the flexibility to offer a variety of deployment scenarios and this also means variety of things to "care about", such as:

- Centralized or on-premises IPT call control (CCM / CME)

- Centralized or on-premises PSTN Breakout

- Gateway selection at customer premises for support of SRST

- IP Addressing

- Security, NAT

- Centralized or Distributed services & bandwidth requirements (e.g. MoH servers, VM)

- QoS

- Call Admission Control

- Centralized or Distributed location of DSP resources for Conferencing, transcoding

You'll choose billing partner depending upon the deployment model and the

involved IPT products. For IPT Billing partners:
