Network Requirements for Cisco Jabber for iPhone and iPad

Network   Requirements

   

If you deploy    Phone Services, the mobile device must be able to connect to the corporate    network.   

    

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. Cisco recommends that you:   
   
  • Verify nonoverlapping     channel configurations, 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:   

    
   
  • The      "VoWLAN Design     Recommendations" section in the      Enterprise     Mobility Design Guide.    
  • The      Cisco     Unified Wireless IP Phone 7925G Deployment Guide.    
  • The      Capacity     Coverage and Deployment Considerations for IEEE 802.11g white paper.    
  • The      Solutions     Reference Network Design (SRND) for your      Cisco Unified      Communications Manager release.    
    
    

If users 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 is dependent on connection quality and cannot be guaranteed.   

    

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.
