Network Requirements for Cisco Jabber for Android

Network   Requirements

   

  

    
  •      
    For optimal     user experience when using Cisco Jabber over your corporate Wi-Fi network, we     recommend that you:     
    • Design your Wi-Fi network      to eliminate gaps in coverage as much as possible, including in areas such as      elevators, stairways, and outside corridors.     
    • Ensure that all access      points assign the same IP address to the mobile device. Calls are dropped if      the IP address changes during the call.     
    • Ensure that all access      points have the same SSID. Hand-off may be much slower if the SSIDs do not      match.     
    • Ensure that all access      points broadcast their SSID. If the access points do not broadcast their SSID,      the mobile device may prompt the user to join another Wi-Fi network, which      interrupts the call.     
          
         
  •      
    Conduct a     thorough site survey to minimize network problems that could affect voice     quality. We recommend that you:     
    • Verify channel      configurations do not overlap, access point coverage, and required data and      traffic rates.     
    • Eliminate rogue access      points.     
    • Identify and mitigate the      impact of potential interference sources.     
          
         
  •      
    For more     information, see:     
    • "VoWLAN Design       Recommendations" section in the       Enterprise Mobility Design Guide.     
    • Cisco Unified Wireless IP       Phone 7925G Deployment Guide.     
    • Capacity Coverage &       Deployment Considerations for IEEE 802.11g white paper.     
    • Solutions Reference Network       Design (SRND) for your Cisco Unified Communications Manager release.     
          
         
  •      

    If you connect to the network remotely, the mobile device must be able to connect to the corporate network using a solid, high-bandwidth connection. Video and audio quality depends on connection quality and cannot be guaranteed.

         

    

Note


   

For services and functionalities supported when connecting to Cisco Unified Communications Manager using Expressway for Mobile and Remote access, see the Supported Services section in the latest Planning Guide for Cisco Jabber.

   
   

Ports and Protocols

The client uses the ports and protocols listed in the following table. If you plan to deploy a firewall between the client and a server, you must configure the firewall to allow these ports and protocols.
