Connecting Yeastar S300 between two hybrid PBS´s

I have a new project. My final client has two hybrid PBS, one Alcatel 4400 and one Samsung OS7200, I need to connect the Yeastar S300 betwenn both PBX as a Tandem.

Samsung OS7200 and Yeastar S300 via SIP TRUNK, and Yeastar S300 and Alcatel 4400 via E1 CAS PRI.

I want to know if Yeastar PRI, has the DC5A signalling, E1 CAS, not ISDN.

Can you send me the main parameters...?

Best Regards


William Ramon
