You can enable the SIP Midcall request timeout and RTCP inactivity settings. Value– Configure UCC session idle timeout in seconds.Ĭonfigures the Session Initiation Protocol (SIP) ALG. This parameter has the following sub-parameters: On configuring this parameter, if the voice session is idle for the configured period, UCM aborts the session on the managed device due to inactivity. This parameter has the following sub-parameters: Įnable– Enable the SCCP ALG on the Mobility Master.Ĭonfigures the UCC session idle timeout. The DSCP value for the voice session is 46 by default. Upstream–Enable upstream Real-Time Analysis of VoIP calls.Ĭonfigures the Cisco Skinny Client Control Protocol (SCCP) ALG. This parameter has the following sub-parameters: Įnable– Enable Real-Time Analysis of VoIP calls. This parameter has the following sub-parameters: Įnable– Enable the NOE ALG on the Mobility Master.Ĭonfigures the real-time analysis of VoIP calls including upstream real-time analysis. Priority–The DSCP value for voice, video, and app-sharing sessions.Ĭonfigures the Alcatel-Lucent® New Office Environment (NOE) ALG. This parameter has the following sub-parameters: Įnable–Enable Jabber ALG on the Mobility Master. The DSCP values for the voice, video, and app-sharing sessions are 46, 34, and 34, Enter the Cisco Unified Communication Manager IM & Presence server IP. This parameter has the following sub-parameters: Ĭhannel-utilization-threshold–The maximum limit for the channel utilization.Įnable–Enable intelligent call handling on the Mobility Master.Ĭonfigures the Cisco® Jabber ALG.

Priority– The DSCP value for the video session.Ĭonfigures the H.323 ALG. This parameter has the following sub-parameters: Įnable– Enable the Apple Facetime ALG on the Mobility Master. SyntaxĬonfigures the Apple® FaceTime ALG. This command configures the various UCC Application Layer Gateways (ALGs). Lastly, please note further tweaking of the policy may be necessary to avoid false positives (i.e.Ich In essence, it is not possible to control Consumer Skype in transparent mode, the application must be set to explicit proxy mode. However, because Consumer Skype does not use valid SSL traffic, the proxy will "break" the connection Consumer Skype is attempting, resulting in loss of connectivity across all the network. SSL interception must be enabled in order to decrypt the encrypted traffic.
In transparent proxy the HTTP CONNECT method is not used. Transparently deployed proxies will not be able to use the above method. However, please note that it is a lot easier to make exceptions for these because, unlike Consumer Skype, they are not peer-to-peer in nature so the destination IPs are easily obtained and added to a whitelist.ģ. This method may have collateral damage on other applications. There may be some enterprise environments with custom built applications that may run into issues, or some forms of IM may break. This method could change at any time because of the closed source nature of Consumer Skype.Ģ. The CPL rules can also be made to apply on certain users and groups only, while allowing access to othersġ.
#SKYPE FOR MAC TIMESOUT CODE#
With the above CPL code in place, Consumer Skype will open but never connect. Instead usually what is observed is " CONNECT " for example. That is to say you almost never see " C ONNECT 192.0.2.1". But when observing normal user traffic, 99% of the time never this traffic never connects directly to an IP. The second rule states "block any CONNECT request made directly to an IP instead of a URL (FQDN)"Ĭonsumer Skype, when it can't connect directly, will fall back to the proxy and will try encrypt connections and try to contact "super nodes", which are usually IP addresses stored in a file in the Skype folder. The first rule simply blocks any host containing "skype" and forces Consumer Skype to go over port 443. The local CPL to use should read:ĭENY thod=CONNECT url.regex=""Īlternatively, the below accomplishes the same:ĭENY thod=CONNECT _numeric=yes
#SKYPE FOR MAC TIMESOUT HOW TO#
For information on how to add CPL to the local policy file, please see 000010101.
#SKYPE FOR MAC TIMESOUT INSTALL#
On the ProxySG install the following CPL into a CPL layer in VPM, or into the local policy file. Step 1 will force Consumer Skype to use the proxy settings taken from Internet Explorer (IE) since it cannot reach other Skype nodes directly.ģ. On the firewall, block all outbound traffic except proxy traffic (this is what most explicit proxy deployments should have)Ģ. Please note that the Skype protocol and application behavior may change at any time.ġ.
The following was tested using Consumer Skype 4.2.x.
