First step into the All-IP world

With All IP, the line is no longer used as a whole, but the individual packets are transported in units via IP.
To ensure consistently good voice quality, the data packets for voice are prioritized with “QoS” (Quality of Service). To ensure that this mechanism works smoothly, it is important to ensure that the Internet bandwidth (in this case the upload) is sufficiently dimensioned. You should generally calculate 100 kbit/s upload per call.
If you make calls in an MPLS, these packets are prioritized with CoS (Class of Service) – the following also applies here: 100 kbit/s per call must be provided.
This connection is of interest to companies with more than 20 employees who need to ensure permanent availability. You can flexibly make up to 30 calls at the same time and increase your capacity as required.
All IP is available nationwide, it is generally cheaper than a conventional PMX connection and still offers all the features of classic ISDN connections.

Provider overview
All IP connection variants
1
Dedicated access: An Internet line for voice-only use.
2
Convergent voice data product: Part of your data line is reserved for telephony using QoS.
3
Combination with Site Connectivity via MPLS: Convergent solution between voice and data.
4
Transfer to data lines from third-party providers: No SLAs on accessibility.
With so many possibilities compared to a conventional PMX connection, questions naturally also arise:
-Which type of connection is right for your company?
-And what else can you connect to your IP connection?

Features of All IP

Regardless of the carrier technology IP or ISDN, you can ALWAYS take your telephone number with you (port it) when changing provider, taking into account the minimum contract term and notice period.
It is also possible to evaluate individual, multiple and centrally managed PMX connections via network-based tools.
Classic add-on services such as clip no screening, CLIR and COLP are still available as well as support for CODEC G.711 / G.729a and also T38.
In a nutshell:
- Number porting possible when changing provider
- Evaluation of PMX connections via network-based tools
- Classic add-on services: clip no screening, CLIR, COLP
- Support for CODEC G.711 / G.729a and T38
All IP costs & AII IP provider
What determines the All IP costs?
One variant that is currently in high demand is use as a convergent voice-data product (combined product). You can simply book this as an option, whereby the monthly costs are significantly lower than for comparable PMX connections, as you no longer need your own line and therefore no additional capacity.
The situation is similar with a connection from the network.
To be taken into account in pricing:
| Factor | Description |
|---|---|
| Location | Provider must ensure availability at your location. |
| Provider | Different conditions and promotions depending on the provider. |
| Dimensioning | The size of the connection depends on you and the upload of your line. |
| Runtime | Longer contract terms often bring better conditions. |
| Features | Different billing models and services, e.g. clip no screening. |
Which All IP providers come into question?
All IP has reshuffled the traditional provider market. In addition to top dogs such as Deutsche Telekom, Colt, Plusnet, Vodafone and others, new providers have also emerged. These are often in no way inferior to the big players – in some cases they outperform them with innovative user guidance and integration options. Keywords: SIP trunks and cloud telephone systems.
A comparison is worthwhile – not only in terms of costs, but also with regard to SLAs, additional options or bundled products such as IP telephony or VoIP.
