SIP Trunk – telephony solution

From ISDN to SIP: modern telephony explained simply
1. SIP Trunk vs. SIP Account
- With SIP trunks, you can manage direct dial number blocks with your IP system.
- A SIP account, on the other hand, only assigns individual phone numbers to the extensions, not a complete block of phone numbers.
2. replacement of classic connections
- SIP trunks replace direct-dial capable system connections (e.g. S0 AnAs, S2M PMX).
- SIP accounts replace the classic ISDN multi-device connections (no analog services).
3. billing and tariff models
- Your telephone number remains assigned to a provider as before.
- Depending on the provider, billing is based on a per-minute or flat-rate model.
4 The decisive difference to ISDN
With SIP trunks, telephony runs directly over the existing data line, making it more flexible, cheaper and future-proof.
With classic ISDN connections, a separate voice line was necessary.

What does SIP Trunk cost?
SIP trunks are significantly cheaper than traditional connections.
While a system connection (for 2 simultaneous calls) costs from approx. 18€ per month, a SIP trunk costs only approx. 0.99€ per month.
However, this is only half the truth. You will certainly need more than one channel and the providers offer different solutions here. Depending on the model, you can get your SIP trunks in packages (i.e. in increments of 10 or 50) or only in conjunction with data lines.
It is difficult to make a general statement about the costs of sip trunks. The following points should be defined in order to be able to make a valid statement about suitable providers and conditions: Number of channels, encryption, contract term, tariff model.
Provider of SIP trunk solutions
SIP trunks have completely shaken up the traditional telephony market. In addition to top dogs such as Deutsche Telekom, Colt, Plusnet, Vodafone and others, a number of new, major international providers have joined the market and are setting new benchmarks in the field of innovative UCC solutions, UX, All IP and cloud telephone systems.
