FAQ
Frequently Asked Questions
How is a DID number different from a conventional phone number?+−
A DID number works through the cloud and SIP Trunk, making it flexible and easy to scale without conventional phone lines. Calls can go directly to an employee or department.
Which telephone systems are supported?+−
DID numbers work with IP PBX and Cloud PBX platforms such as Yeastar P-Series Cloud.
What is a concurrent call?+−
It is the number of calls that can be active at the same time. For example, five concurrent calls allow up to five simultaneous inbound or outbound calls.
Can I add more simultaneous calls?+−
Yes. Concurrent calls can be added as needed, up to the number of extensions in your system.
Where can I use a DID number?+−
Use it anywhere with an internet connection—at the office, at home, or while travelling—when connected to your PBX.
What happens if the internet connection fails?+−
Call forwarding can route calls to a backup number, such as a mobile phone, so important calls are not missed.
Is call recording available?+−
Yes. The optional Backup Voice Record service starts at 5 GB and can store approximately 5,000 minutes.
Why choose a DID number from Call On Cloud?+−
Our numbers are provided directly by National Telecom (NT), supporting reliable call quality and regulatory compliance.
Can I port a number from another provider?+−
Number portability is available for existing SIP Trunk numbers. Analog numbers must first be upgraded to SIP Trunk before porting.
