OneTalk Network Requirements



Verizon OneTalk Network Requirements

The information below shows the ports and protocols used by the Desk phones to register, authenticate and receive service from our network.  If you have any kind of filtering device in your network, Firewalls, IDs, SBC, etc., make sure traffic on these ports is allowed. Please process these ports as trigger ports. The ports should be UDP and TCP unless noted UDP only.  


Desk Phones QoS Details

  • Default Deskphone VLAN - Default vlan is off.
  • DHCP Vlan Option code 132 is used and set by default to allow dhcp to set the VLAN dynamically  (To View on Phone click Menu>Advanced>"admin">Network>VLAN>DHCP VLAN)

  • Local IP Address - The desk phones mac address is assigned a Local IP address via DHCP unless statically assigned by the IT admin (To view IP address assigned to phone click Menu>Status)
  • QoS - Set the switch to look for packets that are marked with DiffServ value EF46
  • Sonic Wall Setup:

1. Go to the VoIP tab (or Firewall tab, depending on the device's web interface) and then VoIP. 

2. Near the top of the page, make sure Enable Consistent NAT is checked.
3. Further down on the page, make sure Enable SIP Transformations is unchecked.
4. Change  UDP timeout to 300 Seconds / 5 Minutes



Problems with dropped Calls when everything else is working correctly?

Make sure your Network Firewall/Router has UDP Timeout set 90 seconds or higher  300 Seconds / 5 Minutes is recommended but may not be needed. 
Sonic Wall and most brands Default to 30 seconds
Mikrotik Defaults to 10 seconds. 

If this doesn't resolve the issue   Please Inform PercFab,  
 Verizon will need multiple call samples.  5 minimum,
Time and date call came in  within 5 minutes accuracy.  (Required)
Phone number of Caller  (Required)
Number the Caller Dialed,  (Required)
Phone Carrier if you know it (Not Required)
any info on why you feel the call dropped (I.e put call on  hold, transferred call, any idea's or speculation why you it happened ) 


Information below is only needed if deskphones do not register to Verizon Network because local firewall is blocking ports:

  • FQDN: 0.pool.ntp.org & time.nist.gov
  • Time Zones are set using the 911 address of record for the device.

Media (voice/video):

  • Protocol: SRTP (the key is negotiated in the SIP session which is encrypted within the TLS tunnel).
  • Protocol: SRTP, Port Range: 14536 to 65535
  • IP Addresses: 69.78.87.164, 69.78.87.165, 69.78.101.228, 69.78.101.229

Ports and Protocols - Desk Phone - One Talk℠


•       The table shows the ports and protocols used by the Desk phones to register, authenticate and receive service from our network.

•       If you have any kind of filtering device in your network, Firewalls, IDs, SBC, etc., make sure traffic on these ports is allowed.

•       During manufacturing, a URL is embedded into the device and once the phone is powered up it tries to reach that URL and initiates all signaling via the specified ports
