Local Network Optimization for VPBX

To ensure optimal connectivity and call quality for your Hosted IP product please apply the following setting within your local network 


  • Ensure SIP ALG or any SIP smart feature is disabled
  • Allow all traffic to 175.158.104.0/22
  • Disable any packet inspection rules for traffic bound to 175.158.104.0/22
  • Reserve sufficient bandwidth for the handsets and ensure traffic bound to 175.158.104.0/22 is prioritized over other traffic


You can also open ports for further optimization 

  • Open ports 5060 and 5061 For Sip Registration
  • Open ports 10500 to 65000 for RTP
