Cisco Unified CallManager 5.0 presents local SIP enlistment center

Executing SIP progressions in an assembled IP network offers different focal points, including extended worth and customer benefit from new and versatile applications, shipper self-rule for more noticeable determination of employments and endpoints, and the likelihood to diminish costs for gear and the organization of exchanges organizations. Cisco is centered around supporting contraptions that have realized standard SIP-based correspondences to bring to the table customers most outrageous endeavor protection, extended choice through interoperability, and more significant sending decisions call manager

Cisco Unified CallManager 5.0 presents nearby SIP selection focus and back to back customer subject matter expert (B2BUA) limits, allowing the affiliation, enlistment, the board, and checking of SIP-based endpoints. The features available to SIP endpoints are practically equivalent to those found in the Cisco SCCP show, allowing SIP and SCCP phones to direct agree and share features. Customers have the chance to move to SIP at their own speed and without the prerequisite for a great deal of customer retraining. Taste is realized locally into focus programming; it isn't executed as an associate course of action, suggesting that the additional cost and unpredictability of discrete applications laborers various vendors use to enlist their SIP phones are not required. Such a nearby consolidation into programming infers it is easier to help and realize, and the costs of keeping a subordinate system are executed. 

The going with SIP-based IP phone models are maintained: 

Cisco Unified IP Phone 7971G-GE 

Cisco Unified IP Phone 7970G 

Cisco Unified IP Phone 7961G-GE

Cisco Unified IP Phone 7912G 

Cisco Unified IP Phone 7911G 

Cisco Unified IP Phone 7905G 

Any outcast SIP phone, fragile phone, or video endpoint that agrees to RFC 3261 and other related RFCs (should encounter the SIP Verified program if affirmation of interoperability is needed); more information about the SIP Verified program is arranged at: http://forums.cisco.com/eforum/servlet/IPCApps;jsessionid=zhyxvhy9f1.SJ2B?page=tpsipep 

Computer correspondence compromise (CTI) maintain for SIP phones—Cisco Unified CallManager 5.0 engages CTI applications to control and screen SIP phones along these lines they have as of late used for SCCP phones. 

SIP trunk-side enhancements—Version 5.0 familiarizes immense redesigns with SIP trunk-side hailing help and call guiding capacities through assistance for the latest RFCs and Internet drafts, including yet not confined to: SIP (RFC 3261), the REFER method (RFC 3515), the REPLACES header (RFC 3891), the Remote Party ID (RPID) header, the Unsolicited NOTIFY procedure, and the SUBSCRIBE/NOTIFY strategy. Taste trunk-side frameworks organization gives an open interface to applications to interface to the Cisco Unified CallManager 5.0. 

REFER maintain—Supported by Cisco Unified CallManager 5.0 for SIP-began moves; these trades are done from the Cisco Unified CallManager or from an outcast application 

Replaces header—This improvement is used to displace a current SIP trade with another; the ability to change the header is a component of the Cisco Unified CallManager being a B2BUA. 

Subscribe/illuminate event declaring—This redesign is open on the SIP trunk for use by external applications, for instance, the Cisco Unified Presence Server to report presence to an external component.

On the same screen, scroll down to the SDP Profile Information section. The SDP Session-level Bandwidth Modifier for Early Offer and Re-invites option is set by default to TIAS and AS. Change this option to TIAS only. If you leave this option at its default setting, Skype for Business Server will not understand the bandwidth modifier information in the SIP message. TIAS means Transport Independent Application Specific while AS means Application Specific. These are SIP options specified in RFC3890.

On the same screen, scroll down further. Under the SIP Profile's Trunk Specific Configuration, select Early Offer Support for voice and video calls and set it to the Mandatory (insert MTP if needed) option. This will enable CUCM to set up an outgoing SIP call with Early Offer. One new feature in CUCM 8.5 and beyond is that it supports outgoing call setup with Early Offer without requiring Media Termination Point (MTP).

Verify that in the SIP Options ping section, the box is checked next to "Enable OPTIONS Ping to monitor destination status for Trunks with Service Type 'None (Default)'."

When you are finished, click on Add New.

Fog computing: what role for the IoT?

Definition of fog computing

Fog computing, also called "computing in the fog", defines an infrastructure responsible for storing and processing data from connected objects . Direct competitor, alternative or complementary solution to cloud computing, fog computing has the particularity of storing and processing data through the use of equipment located at the edge of the network. It therefore makes it possible to carry out these two actions locally, without having to request a datacenter located several hundred kilometers away or a cloud. In this area of ​​storage and processing of data and IoT, fog computing creates an additional interface that can be situated between Edge Computing and Cloud Computing.

Fog VS edge computing

Fog computing and edge computing are two quite similar infrastructures. Both are based on the processing of data produced directly by objects connected at the edge of the network. This proximity to the point of origin leads to a significant reduction in latency (more travel between the connected object and the cloud). The difference between fog and edge computing is the IT equipment involved: according to the OpenFog Consortium, edge refers to processing terminals while fog computing refers to IT architecture. In addition, we speak of edge computing when the computing resources are in the connected object, and fog computing when they are in a separate network node, such as an IoT gateway. 

Fog computing actively participates in decongesting network traffic (only the most important information is transmitted to the company's servers) and in increasing its performance (notably by reducing bandwidth consumption). Finally, it should be noted that fog computing is also intended to strengthen data security. By storing them securely locally, it limits possible intrusion attempts and prevents cyber attacks against the cloud or data centers.

Cisco voice engineer jobs

It is now accepted to say that we owe the concept of fog computing to an engineer at Cisco Systems, an American computer company specializing in servers. Since 2015, there has also been the OpenFog consortium (which brings together companies such as Cisco, Dell, Microsoft and even ARM) responsible for defining network protocols and technological standards useful for market standardization. The objective: to succeed in giving a definition of distributed architecture that can be able to adapt to the very strong development of the IoT. On the technical level, the fog computing infrastructure is made up of several layers, respecting the stacking logic that is already found in the cloud, into which its own elements are then integrated,

The modes of access to his voice mail

Unified communication at the heart of all exchange processes is undoubtedly a time saver in productivity and working comfort. You can therefore consult your voicemail using the following different access modes:

From his landline

Visual Voice Mail makes it possible to navigate graphically in the interface to consult the messages left at any time.

From the unified client

The Cisco Jabber or Lotus Sametime client or even Lync are just some of the ways to access your voice messages.

From the Email client

The messaging clients can be used to consult its voicemail messages but also to classify and archive them. The transfer is done by the IMAP client or by RSS feed. In this case, the Business Edition 6000 solution ensures consistency between text and voice messages, an undeniable advantage in many cases and a substantial gain in productivity for employees.

In mobility

Mobility situations are not to be outdone. It is of course possible to consult your voicemail messages from your mobile via the Personal Communications Assistant (PCA) web portal, or the unified messaging web portal or the Jabber Client.

Critical bug 9.9 / 10 at Cisco: Quickly fix this hole in Jabber for Windows and MacOS

Watchcom reported four vulnerabilities to Cisco earlier this year

According to Cisco, the bugs allow an attacker "to run arbitrary programs on the underlying operating system with elevated privileges or to access sensitive information." Customers have no choice but to install the latest updates to prevent attacks voice engineer jobs.

Norwegian security firm Watchcom discovered earlier this year that Jabber was vulnerable to a cross-site scripting (XSS) attack through XHTML-IM messages. Jabber did not properly sanitize incoming HTML messages and instead passed them through a faulty XSS filter.

Cisco notes that new message processing vulnerabilities can be exploited if an attacker can send Extensible Messaging and Presence Protocol (XMPP) messages to end user systems that are running Cisco Jabber. "Attackers may need access to the same XMPP domain or another access method to be able to send messages to clients," Cisco notes in a notice .

The three partially fixed bugs are tracked as CVE-2020-26085, CVE-2020-27127, and CVE-2020-27132.

Watchcom reported four vulnerabilities to Cisco earlier this year, and they were revealed by the network giant in September. But three of them weren't properly fixed in updates at the time, according to Watchcom.

Failed mitigation

Watchcom reviewed the fixes after a customer requested an audit to verify that the bugs had been sufficiently mitigated in existing Cisco fixes. He found that the bugs had not been mitigated.

Two of the three poorly fixed bugs can be used to achieve remote code execution. One of them can also be used to get NT LAN Manager (NTLM) password hashes from users.

“Two of the vulnerabilities are due to the ability to inject custom HTML tags into XMPP messages,” says Watchcom penetration tester Fredrik Bugge Lyche. “The patch released in September only patched specific injection points that Watchcom had identified. The underlying problem has not been addressed. We were therefore able to find new injection points that could be used to exploit vulnerabilities
