SIP (Session Initiation Protocol) Trunking connects IP PABX devices to a telephone exchange using the SIP protocol for communication over an IP network. This provides a more flexible and scalable communication system than traditional telephone lines.
1. Scalability:
SIP Trunk services can scale your internet connection to match your maximum call volume. The required bandwidth will depend on the type of media (voice, video, text), and if you have multiple locations using the same provider, calls between locations will be free of charge.
2. Value for money:
Using a SIP trunk can scale your internet connection to match your maximum call volume, reducing communication costs and eliminating the need for multiple phone lines.
3. Increased reliability:
SIP trunk numbers offer higher reliability than traditional analog circuits because they are designed to ensure your digital phone connection has sufficient bandwidth for high-quality calls, and utilize automatic call quality improvement technologies such as echo and noise reduction. You don’t have to worry about dropped calls or echoes during connection; enjoy consistently high-quality voice calls over the internet, reducing downtime and ensuring smooth communication.
4. Geographic flexibility:
SIP trunk numbers are independent of local switching services, so you can have any number regardless of your business’s physical location. Furthermore, if you move, you can take your phone number with you wherever you go.
1. Flexible scaling:
Start your business with a minimum of just 5 lines. Easily adjust the number of lines to suit your business needs and choose attractive and auspicious phone numbers for your business.
2. Cost savings:
Save on infrastructure costs and reduce your overall communication expenses.
3. High quality:
Experience clear, smooth, and uninterrupted voice calls.
4. Easy integration:
It can connect to your existing PBX system.
Mobile numbers used for making calls to designated or prospective customer groups can provide proactive information services, including:
1. You can request to open a mobile phone number starting from 1 number.
2. There is no limit on the number of lines that can be used for outgoing calls.
3. You can randomly generate dialing numbers.
A SIM Gateway is a device that enables the use of SIM cards for making calls via VoIP (Voice over Internet Protocol). Renting a SIM Gateway allows your business to utilize mobile network provider promotions to control your outgoing call costs as needed.
1. The SIM gateway service is a monthly rental service; no equipment investment is required.
2. The minimum rental service starts at 1 slot for depositing SIM cards for making calls.
3. You can limit call charges according to your SIM card package, allowing you to control your expenses.
