Configuring Business-to-Business SIP URI dialling with Expressway

Posted by Dishko Hristov on Jul 7, 2016 8:30:00 AM

If you already have Expressway MRA and SIP URI dialling activated in your Cisco Unified Communications environment, then you should seriously begin to think about activating another very key feature within Expressway: Business-to-Business dialling. This feature will bring your collaboration with your partners and customers to whole new level; allowing you to have audio, and have video calls with them as seamlessly as you do this with your coworkers.

A big part of the configuration process for B2B calls is deploying public DNS SRV records that will allow your partners and clients to call you using your corporate domain. Assuming you have all necessary ports on the firewall already opened, since this is part of your Expressway MRA deployment.  The following will take you throught the steps required to effectively configure the B2B SIP URI dialling feature within Expressway.

Diagnosing Firewall "Misbehaviour" with Packet Captures

Posted by John Marrett on Jun 22, 2016 8:30:00 AM

Our support team received a call from a customer complaining that their next generation firewall (NGFW) was intermittently blocking access to their new voting website. As we were in the process of making firewall changes inside their environment and are responsible for the management of their network they turned to us for help.

The website was a vanity domain hosted at GoDaddy that redirected users to a deep link within another website. We accessed the site and confirmed that it was working properly and sending a 301 redirect as expected, it worked properly both inside their and our environment. We reviewed the firewall logs and found no indications that traffic was blocked by any firewall or IPS. The customer insisted that there was an intermittent problem accessing the website that seemed to affect some users at random.

Transform how you Interact with your Customers Using Cisco UCCX.

Posted by Eric Losier on Jun 9, 2016 8:30:00 AM

 

Like most Cisco Unified Communications customers with the need to support some form of contact center within their organizations, you may have most likely deployed Cisco Unified Contact Center Express (UCCX), or perhaps its big brothers Packaged Contact Center Enterprise (PCCE) or Unified Contact Center Enterprise (UCCE). And again, like most Cisco contact center deployments, you have most likely initially focused on the essentials: getting your agents to answer customer calls! Now that this is out of the way, it’s time to take a deeper look under the hood of your Cisco contact center platform and realize its true potential: it can completely transform how you interact with your customers. 

Although PCCE and UCCE platforms are great, this article will focus on UCCX. With the capacity to support 400 agents and as many concurrent IVR ports, UCCX fits most small and medium-sized organizations. At its core, it consists of four main modules all within the same box: an Interactive Voice Response (IVR) system, an Automatic Call Distribution (ACD) engine, a set of applications for Computer Telephony Integration (CTI), and a Reporting platform. At first glance, this may all seem relatively standard. However, what sets UCCX apart is its flexibility; at Stack8, we consider UCCX to be closer to a Telephony Application Development platform than a contact center product.
