Before you can deploy a SIP trunk, you and your service provider must exchange some basic connection information about your respective SIP trunk end points.
Get the following information for each service provider proxy (SPP) you will connect to:
- IP address
- FQDN
 Note: |
|---|
| The service provider may have you connect to more than one SPP. In that case, you must configure a connection between each SPP and each server in your pool. |
The information you give to your service provider depends on your SIP trunk connection type:
- For MPLS or private network connections, give them the publicly
routable IP Address of your perimeter network (DMZ) router. Verify
that the SPP can reach this address. Also give them the SIP domain
FQDN (the FQDN of your server pool).
- For VPN connections, give them the IP address of your VPN
server.
| Note: |
|---|
| You must set up at least one SIP trunk for every server in your pool. |
Deployment Process
To implement the Communications Server 2010 side of the SIP trunk connection, follow these steps:
- Using the Communications Server Deployment Builder, create and
configure the SIP domain topology.
- Using the Communications Server 2010 Control Panel, configure
voice routing for the new SIP domain.
- Test connectivity.
