We are proud to announce that Signum telekom has become a Yeastar certified SIP trunk provider (ITSP partner). Our SIP trunk has passed Yeastar’s testing and certification, and Signum has become the only domestic certified SIP Trunk and Cloud_PBX provider in Croatia!
What does Yeastar certification mean?
Yeastar is one of the world’s leading manufacturers of business phone systems, and its PBXs are used both in the cloud and on premises. Through its ITSP partner programme, Yeastar checks that a provider’s SIP trunks work correctly with its phone systems – from registration and outgoing and incoming calls to codecs and the transmission of touch tones.
For users, this means peace of mind: Signum’s SIP trunk and Yeastar phone systems are proven to work together, with no guesswork about settings and no surprises after switching.
What was tested
- Trunk type: register-based trunk, on all Yeastar phone system models.
- Codecs: G.711 (alaw and ulaw), G.722 for HD voice and G.729 to save bandwidth.
- Touch tones (DTMF): RFC2833, SIP INFO and inband – so IVR menus and PIN entry work reliably.
Yeastar has also published a guide to setting up a register-based SIP trunk (using a P-Series PBX as an example), so connecting Signum’s trunk to your phone system takes just a few minutes.
Who is this for?
If you already use a Yeastar phone system – in the cloud or on your own server – you can connect Signum’s SIP trunk to it and keep your existing numbers, with lower call costs and as many voice channels as you actually need. If you are still choosing a phone system, Signum Cloud_PBX gives you a Yeastar PBX and a SIP trunk from the same partner, backed by our technical support.
