Connectivity
In many cases, when businesses upgrade their communications they take the opportunity to move their PABX to the cloud. SIP trunking is usually compatible with this, but if you want to retain your old in-house PABX, you need to ensure that it’s going to work with the new SIP channel. Many providers will carry out interoperability testing to help you ensure that your equipment will continue to work smoothly after you switch.
If you have multiple sites, SIP is denmark telegram of value here too. It’s possible you have existing ISDN connections between sites; these are inflexible – limiting the number of lines available – but also have relatively high rental costs. Switching to SIP means that you can reduce the number of connections and also the cost. It also means that you don’t need to maintain a PABX at each site, you can centralise the operation in one place or in the cloud.
One of the major drawbacks of older systems is that ISDN lines limit the number of lines you can have on each connection. Expanding that means renting another line.
SIP trunking offers you far more flexibility. If you are a business that experiences seasonal peaks, you no longer need to pay for extra capacity that will lie unused for most of the time. You can quickly and easily add or remove trunks as needed to cope with demand.
There’s also flexibility in numbering when using SIP. This means that you are free to move premises and keep your old numbering, even if your new base is in a different exchange area. You can use this to your advantage if you operate in different parts of the country too, ensuring that your customers have a local number to call, even if that call is actually answered centrally elsewhere.
