4.4.4.3 For modem support – the UC500 supports G.711 upspeed via proprietary
methods – support is being added to Cisco IOS to upspeed to G.711 via a SIP re-
Invite as proposed in SIPConnect forum.
4.4.5 Outbound proxy support
This feature allows the UC500 to send all SIP packets to a specific IP address or DNS
instead of the IP / DNS of the proxy server defined in section 4.3.20. This is a common
method used in case the SP has an SBC (Session Border Controller) which interfaces
with all customer IP PBXes from the SP point of view.

outbound-proxy dns:sipconnect.cisco.com
Note: If outbound proxy is used, you cannot use SIP phones (such as Cisco 3911 or
3951) till UC520 software pack is upgraded to 4.3.x. Also, since the interface between
UC500 & CUE (voicemail / AA) is also SIP – make sure all VOIP dial-peers on UC500
pointing to CUE have the below added:

4.4.6 Call Admission Control (CAC) & QoS
Since calls over SIP Trunk are using the IP interconnect, there is no implicit CAC setup
like you would have with TDM trunks such as timeslots on a T1 PRI. To allow for this
