RFP Template

1 IP Phones
1.1 All IP phones shall support RTP with RTCP SR/RR (IETF RFC3550). If IP phones implement Secure RTP (IETF RFC3711)then RTCP SR/RR and XR reports must be transmitted unencrypted.

1.2 Monitored IP Phones shall support RTCP XR VoIP Metrics (IETF RFC3611). ITU G.107 and ETSI TS 101 329-5 Annex E (VQmon) shall be used to generate call quality metrics. All parameters of RFC3611 Section 4.7 must be supported.

1.3 Monitored IP Phones shall support the appropriate signaling based QoS reporting protocol - H.460.9 Annex B for H.323, draft-ietf-sipping -rtcp-summary-02.txt (or later draft) for SIP.

2 IP Gateways
2.1 All IP gateways shall support RTP with RTCP SR/RR (IETF RFC3550). If IP gateways implement Secure RTP (IETF RFC3711) then RTCP SR/RR and XR reports must be transmitted unencrypted.

2.2 Monitored IP Gateways shall support RTCP XR VoIP Metrics (IETF RFC3611). ITU G.107 and ETSI TS 101 329-5 Annex E (VQmon) shall be used to generate call quality metrics. All parameters of RFC3611 Section 4.7 must be supported, in accordance with ITU G.799.1.

2.3 Monitored IP Gateways shall support the appropriate signaling based QoS reporting protocol - H.460.9 Annex B for H.323,draft-ietf-sipping -rtcp-summary-02.txt (or later draft) for SIP or H.248.30 for Megaco.

3 Probes/ Analyzers
3.1 Probes and analyzers shall use ITU G.107 and ETSI TS 101 329-5 Annex E (VQmon) to generate call quality metrics for packet based non-intrusive or active monitoring.

3.2 Probes and analyzers shall support the detection and analysis of RTCP SR/XR (IETF RFC3550) and RTCP XR (IETF RFC3611) VoIP Metrics payloads, including the extraction of parameters related to delay, signal/noise level and endpoint configuration.

4 Embedded SLA Monitoring Function in Routers
An Embedded SLA Monitoring Function is a software agent installed in a service provider managed edge router, multi-service gateway or integrated access device located on the customer premise. The purpose of the SLA Monitoring Function is to support the measurement of service level received by the customer, and to permit the service provider to implement some level of remote diagnostics. This is achieved by gathering statistics on live customer traffic and by implementing active testing for both inter-site monitoring and on-demand troubleshooting.

4.1 Edge Routers, IADs and Multi-Service Gateways shall incorporate an integrated passive VoIP monitoring function using ITU G.107 and ETSI TS 101 329-5 Annex E (VQmon) in order to monitoring the quality of VoIP traffic delivered to/from the customer premise.  Such edge devices may also incorporate an active test function to support SLA monitoring and on-demand troubleshooting.
