General Questions

Q. What is the Cisco ® 1861 product family?
A. The Cisco 1861 and Cisco 1861E, which are part of the Cisco 1861 product family and from the Cisco 1800 Series Integrated Services Router (ISR) portfolio, is a unified communications solution targeted at small and medium-sized businesses (SMBs) and enterprise small branch offices. This solution provides voice, data, voicemail, Automated-Attendant, video, and security capabilities while integrating with existing desktop applications such as calendar, email, and customer-relationship-management (CRM) programs. This platform takes full advantage of business-class, proven unified communications technologies and supports flexible deployment models based on your needs - a wide array of IP phones, public-switched-telephone-network (PSTN) interfaces, and Internet connectivity.
Core components include the following:

Cisco Unified Communications Manager Express (CME) or Cisco Unified Survivable Remote Site Telephony (SRST) for call processing

Cisco Unity® Express for voice messaging, Automated Attendant (optional), and TimeCardView (TCV)

Integrated LAN switching with Power over Ethernet (PoE) support - expandable through Cisco Catalyst® switches

Optional security with firewall, VPN, Secure Sockets Layer (SSL), and intrusion-prevention-system (IPS) capabilities

Note: Henceforth Cisco 1861(E) will refer to both Cisco 1861 and Cisco 1861E models, unless these models are called out explicitly. Cisco 1861 will refer to Cisco 1861 models only; Cisco 1861E will refer to Cisco 1861E models only.

Q. What are the differences between the Cisco 1861 and Cisco 1861E?
A. The Cisco 1861E comes with default DRAM of 512MB compared to 256MB on the Cisco 1861. Also there is no Wireless LAN support on the Cisco 1861E.
Q. How are the Cisco 1861(E) products packaged?
A. As shown in Table 1 and 2, the Cisco 1861(E) packaging was created for ease of ordering and communication. The Cisco 1861(E) is targeted at the 8-user market segment. From a packaging perspective, it is organized as follows:
