    Resources & FAQ

    Frequently Asked Questions

    Can I terminate my ISDN subscriptions immediately?

    You can terminate your ISDN subscriptions with your actual telephony provider as soon as all numbers have been ported to ALLOcloud. In general this takes about 10 days and in the meantime your ALLOcloud partner or service engineer will configure your telephony set-up and infrastructure.

    How can I order additional devices and numbers?

    To order additional devices and numbers, please contact your ALLOcloud integration partner or account manager.

    Can I keep my existing numbers?

    Yes. Your numbers will be ported from your existing telephony provider to ALLOcloud. After the portation of your number you will benefit up to 80% cost savings on your call traffic.

    Do I need to change my existing telephony infrastructure?

    Next to cost reduction, the main advantage of SIP Trunking is that you do not need to change your existing infrastructure. We guarantee a smooth transition without any impact on your users.

    In which countries can I get an international number for my contacts abroad to reach me? (+1, +33, ...)?

    Your international contacts can call you on a local number (+1, +33, +44, ...). We offer international numbers in over 60 countries.
