atcomsystems.ca/forum Forums TDM Business Telephone Systems Samsung Telephones & Systems SIP - Can dial OUT but not IN

We've recently switched over from PSTN to a SIP trunk service.

We're having 2 PSTN numbers ported to the SIP, had our backup line moved first in case we run into a problem (like now!)

Our supplier doesn't offer technical support for the Officeserv system so we're abit on our own. I has an engineer initially setup the system and everything seems ok but ive since realised...

We can't dial INTO our number unless we've previously dialed OUT within the last couple of minutes.

Its as if the connection between the SIP server and Officeserv gets terminated.

Ive also noticed it takes almost 10 seconds between dialing the number to it actually dialing out, we get a message saying ALERT_IN then it dials.

If these are any help, i can post other screens if needed.



Eventhough DID Ringing is set to ring Port 517 (Auto Attendant) it doesnt! just rings 500



Any help would be appreciated.

Thanks,
Ashley
