Hi All I currently have an issue with making outgoing calls via SIP Skype ITSP. I have a working SIP ITSP but I would like to get familiar with SKYPE. The SIP-UA with SKYPE is registered and can bee seen as registration status ok when I browse to the SKYPE Manager web page. Incoming calls are successful however outgoing calls fail with the following error detailed below. The disconnect Cause code found in the  VOIP CCAPI trace, relates to SIP Proxy Authentication error,  found within the CCSIP trace Messages during the setup of the call. Disconnect Cause (CC) : 47 Disconnect Cause (SIP) : 407 Received: SIP/2.0 407 Proxy Authentication Required From: <sip: 9905XXXXXXXXXX@76.63.XX .01>;tag=37D7EF0-13F3 To: <sip: 44789xxxxxxx@sip.skype.com >;tag=44da78c1-13c4-5071c43f-e8a4c7dd-2087e3ba Call-ID: 506A1FDE-FE011E2-B83AD438-7F20DAC@76.63.XX .01 CSeq: 101 INVITE Proxy-Authenticate: Digest realm="76.63.XX.01", nonce="5071c45d00012d3e6e3d6c88ebd5ca4ab8e97b136a45bbee", algorithm=MD5 Via: SIP/2.0/UDP 76.63.XX.01:5060;branch=z9hG4bK9137C86 Content-Length: 0 The fault is active on the IOS 15, if I roll back to IOS 12, the outgoing SIP calls are successful. Please be advised Cisco have introduced the following with the IOS 15 Train Multi-registrar’s url below: http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-multi-registrars.html. This allows users to have a choice of several SIP ITSP connected to their CUBE. I have tried several IOS 15 train all with the same results, when initiating a call with Skype. With reference to the issue I’m currently facing. I have a SIP Dial-peer from HQ and an E-Phone currently configured on HQ. Incoming calls is reaching the E-Phone successfully, however outgoing calls are failing. The Outside facing interface on the HQ Router is configured for NAT. I have decided to configure the SKYPE SIP configuration on my Voice Router GRY9, and connected to the HQ Router. I have completed the same configuration for the Remote site Router CUBE. Both of these Voice Gateways, incoming and outgoing calls to Skype are successful. The only difference in the configuration relates to the HQ Perimeter facing Router which is configured with NAT, although I dont believe this to be an issue. I run a debug CCSIP Call, you will see in the setup message “State Dead” and the Source Address is My Perimeter Public facing IP address. If I debug the GRY9 and the CUBE voice gateways you see the internal IP address associated to the Voice Router interface. The IP address subnet range for the routers are actually configured Subnet’s (Subinterfaces ) “Nat Inside” off the HQ. perimeter router. During the SIP Call setup process i.e. "Sent invite", "Received Trying"   The Proxy-Authenticate Digest realm, fails to populate the SIP ITSP DNS name. All that is populated is the IP address. i.e. “ 76.XX.XX.01@sip.skype.com ” or “76.xx.xx.01@sipgate.com ” The SIP-UA, Authentication username and password are correctly configured not sure how to resolve the issue. Please review attached debug documentaion which highlights a successful call via two SIP ITSP on a 12T train an the failed call to Skype on the 15T. Please note the second ITSP calls is successful on the 15 Train, the issue relates to SKYPE calls only. ... View more

Hi All, Need a littel help with  getting Multicast Video Streaming to work across my Development Network, utilising VLC. I have a 2811 Router configured with a "NME-16ES-1G-P: EtherSwitch SM 16 10/100T PoE + 1 GE Port adapter, 1 port". which is the equivalent of a 16 Port 3750 Catalyst POE. My 2811 is configured with Sub-Interfaces, which is connected to a Trunk port on the 3750 Module. *     The 2811 is configured for Multicast-Routing *     The Sub Interfaces are configured with IP PIM Dense-Mode *     The Sub Interafaces are also configured to Join the Multicast Address 224.1.1.1, 224.1.1.2 & 224.3.3.3 The Issue I have is as follows: 1)     If I Ping one of the Multicast Address i.e. 224.1.1.1 from a Host on a switchport connected to either vlans, and display the Mroutes,         the 2811 Router Sub-Interfaces configured with PIM, join the multicast group. (10.1.1.10, 224.1.1.1), 00:00:06/00:02:59, flags: LT   Incoming interface: FastEthernet0/0.10, RPF nbr 0.0.0.0   Outgoing interface list:     FastEthernet0/0.20, Forward/Dense, 00:00:06/00:00:00     FastEthernet0/0.300, Forward/Dense, 00:00:06/00:00:00 (172.16.1.10, 224.1.1.1), 00:01:39/00:02:29, flags: LT   Incoming interface: FastEthernet0/0.20, RPF nbr 0.0.0.0   Outgoing interface list:     FastEthernet0/0.300, Forward/Dense, 00:01:39/00:00:00     FastEthernet0/0.10, Forward/Dense, 00:01:39/00:00:00 2)     However if I apply the same priciple with streaming Video using VLC with the same IP Address, the Sub-interfaces configured with PIM, do not   see   the traffic. I am of the opinion the 3750 switch ios not broadcasting / Multicasting the Streaming Traffic. I can pickup the Video stream if I connect a host which is configured in the same Vlan as the Source.
