Please contact [Technical Support](https://go.servicetitan.com/#/ask) for details. ## Things to know - Dialpad does not support virtual private networks (VPNs). If your company uses a VPN, set up a Split tunnel and direct Dialpad traffic outside of the VPN. - You can use a virtual LAN (VLAN) for managing security and routing policies. You can also use a voice VLAN for security purposes. > [!NOTE] > **Note:** You are required to set up a voice VLAN when workstations are linked together through IP phones. - For better voice quality, we recommend using either a high-speed DSL, cable, or fiber-optic connection with dedicated upload and download bandwidth for the voice of at least 100 kilobits/second for each voice line you plan to run. ## Set wired connections Wired connections provide the best quality experience. Your network should use cabling that meets the network speed specifications. ## Set wireless connections If you use a wireless connection, be aware of the following issues: - Physical obstructions - Channel congestion - Electromagnetic interference - Multiple Wi-Fi bandwidth frequencies - Type of frequency for wifi connection ## Router options Phones Pro supports network routers, switches, and firewalls. Make sure your network hardware supports the following features: - Quality of service (QoS) - Bandwidth limiting - Simple Network Management Protocol (SNMP) We recommend turning off the following features: - Session Initiation Protocol Application Layer Gateway (SIP-ALG) - Deep Packet Inspection (DPI) - Stateful Packet Inspection (SPI) ## Enable QoS For supported routers, you can configure QoS settings based on: - Application (RTP/SIP) - Application and port (RTP over UDP) - Destination port - Combination of the options listed above ## FQDNs Routing to a Fully Qualified Domain Name (FQDN) allows modern Cloud Networks flexibility for Routing, Security, System Maintenance, and remote Device management. Dialpad uses FQDNs for: - Registration - Exchanging SIP to set up a call - Managing Device Firmware - Managing Device Configurations - Managing Devices remotely Dialpad recommends the following FQDN: - dialpad.com - www.obitalk.com - www1.obitalk.com - prov.obitalk.com - devpfs.obitalk.com - storage.googleapis.com - ubervoice.ubervoip.net - turn.ubervoip.net - stun.l.google.com - uvwss.ubervoip.net - legacy.dialpad.com - dialpadcdn.com - static.dialpadcdn.com - prov*.dialpad.com - realtime.push.dialpad.com - realtime2.push.dialpad.com - realtime3.push.dialpad.com - *.dialpad.net > [!NOTE] > **Note:** You can view Dialpad's traffic flagged with Differentiated Services Code Point (DSCP) markings (for example, DSCP 46 = RTP Traffic). ## Ports and protocols See the list below for recommended ports and portals: Desktop native, mobile, and browser applications: ![Table displaying traffic types, protocols, domains, and associated ports for network communication.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/phones-pro-network-recommendations-and-setup-image-lkll816y.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A36%3A55Z&se=2026-10-31T03%3A36%3A55Z&sr=c&sp=r&sig=O9GKnLQYINn%2BFYdFtgioTG8pswXRLcudIi5BVoQ9egE%3D) Poly desk phones (Obi-Edition and UCS): ![Table displaying traffic types, protocols, domains, and ports for network services.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/phones-pro-network-recommendations-and-setup-image-lg0slus0.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A36%3A55Z&se=2026-10-31T03%3A36%3A55Z&sr=c&sp=r&sig=O9GKnLQYINn%2BFYdFtgioTG8pswXRLcudIi5BVoQ9egE%3D) ## Open ports Use the following ports to exchange data, register, and exchange media with Dialpad servers: ![Table displaying port numbers, protocols, and their respective notes for network communication.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/phones-pro-network-recommendations-and-setup-image-w2caejwa.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A36%3A55Z&se=2026-10-31T03%3A36%3A55Z&sr=c&sp=r&sig=O9GKnLQYINn%2BFYdFtgioTG8pswXRLcudIi5BVoQ9egE%3D) Open the following ports for **Obihai** and **SIP Phones**: ![Table listing ports, protocols, and notes for Obihai devices and connections.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/phones-pro-network-recommendations-and-setup-image-tliqxwtq.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A36%3A55Z&se=2026-10-31T03%3A36%3A55Z&sr=c&sp=r&sig=O9GKnLQYINn%2BFYdFtgioTG8pswXRLcudIi5BVoQ9egE%3D) > [!NOTE] > **Note:** If you have outbound port restrictions, make sure you have Port 10000 to 20000 open under Protocol UDP/TCP. ## Want to learn more? - See [Phones Pro](/construction/docs/phones-pro-home) ServiceTitan's integrated phone system that routes calls, records conversations, and connects call data to job and customer records. **What it does:** Gives businesses a CSR productivity platform with call tracking, recording, and booking analytics built into the same system as their jobs. **Also called:** ST Phones, Integrated phone system **Tags:** Phones Pro [See the full glossary โ†’](https://help.servicetitan.com/docs/glossary-overview) Split determines how much credit each technician is getting for the job. For example: If two technicians perform work on a job, the split could be an even 50%-50%, or it could be 75%-25% if the first technician did a bulk of the work. By default 100% of the technician split will go to the first technician assigned to the job.
