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 175.158.106.0/24
• Disable any packet inspection rules for traffic bound to 175.158.106.0/24
• Reserve sufficient bandwidth for the handsets and ensure traffic bound to 175.158.106.0/24 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
