CM 5.0 Sip trunk to VoIP Provider with digest

I have a call manager server with SCCP phones and would like to trunk it to an external voip provider. Reading the Security Guide for the CM to act as a UAC you need to add a realm but unsure how this comes into play when the request goes out. Any references or notes would be great. Thanks

Cisco CallManager SIP Trunk Integration

Cisco Unity Connection 1.1 supports a SIP trunk integration with the Cisco CallManager phone system when the Cisco CallManager phone system has only SIP phones. Refer to the Cisco CallManager 5.0 SIP Trunk Integration Guide for Cisco Unity Connection for more detailed information. The following list describes a few tips that should be performed from the Cisco CallManager Administration side when integrating the Cisco CallManager phone system with Cisco Unity Connection by a SIP trunk:

?Create a SIP trunk that points to Cisco Unity 4.2 and ensure that "Redirecting Number IE Delivery - Outbound" is checked. This instructs Cisco CallManager to send the Diversion Header to Cisco Unity, so you access the correct voice mailbox. Refer to "Trunk Configuration" in the Cisco CallManager Administration Guide.

?Assure that your phones support DTMF Relay as per RFC-2833. Cisco Unity will support both OOB and RFC-2833. For more information on compatible versions of the TSP, refer to the Compatibility Matrix: Cisco Unity Connection, the Cisco Unity-CM TSP, and the Cisco CallManager Express documentation.

?Define a route pattern (for example, 7555) and point that route pattern to the SIP trunk to Cisco Unity. Refer to "Route Pattern Configuration" in the Cisco CallManager Administration Guide.

?Define a voice mail pilot (for example, 7555). Refer to "Cisco Voice-Mail Pilot Configuration" in the Cisco CallManager Administration Guide.

?Define a voice mail profile (for example, VM Profile 1) with the voice mail pilot that you defined in the previous step. Refer to "Voice-Mail Profile Configuration" in the Cisco CallManager Administration Guide.
