FAQ
Do you have more questions about the TKD Trunk? We have compiled the most frequently asked questions and provided answers. If you have any further questions, please contact us, and we will provide information in a non-binding consultation.
What is the TKD Trunk?
Voice product with zero, one, or multiple phone numbers and a desired number of voice channels. Additional options in the TKD account include fax2mail / mail2fax (virtual fax server solution), free fallback to mobile phone in case of internet connection failure, and more.
Is the TKD Trunk reliable?
We encrypt our Trunk with SRTP upon request and offer various permission classes for call areas (examples: only Germany, only landline and mobile, special numbers yes/no, international calls yes/no). Each Trunk is protected with a secure, long, and complex password. We establish a maximum limit for individual call costs (standard: €80). If this limit is reached, the entire Trunk is temporarily blocked for outgoing calls until reactivation by our technical team in coordination with the end customer.
Is it possible to obtain a new telephone number with the SIP Trunk?
Yes, upon request, we provide our customers with a fresh direct dial-in number (with block) from the customer’s area code network at no additional cost.
Can I port my existing phone numbers?
Yes, a phone number always belongs to our customers and can therefore be ported to the TKD Trunk without any issues.
How many concurrent calls can I handle over a SIP Trunk?
Currently, there is no upper limit on the number of concurrent voice channels per TKD Trunk. Our customers can start with as few as 1 voice channel.
What do I need to use the TKD Trunk?
The TKD Trunk, like any trunk, is purely a voice landline product, not a full telecommunications solution. The TKD Trunk ALWAYS requires an internet connection, whether in a data center or at our customers’ premises. To operate the TKD Trunk, a separate telecommunications solution is necessary. This can include:
– IP-capable PBX (Private Branch Exchange)
– Session Border Controller (SBC)
– A single SIP phone
– And more (FritzBox, voice-capable routers, etc.)
Which telecommunications solutions are compatible with the TKD Trunk?
- All IP-capable telephone systems
- Session Border Controllers (SBC) for Microsoft Teams
- Individual SIP phones for direct connection
- And more (FritzBox, voice-capable routers, etc.)
