Call cannot go through

[Shahril]

Hi all

I have a problem that when I try to call this one DID number, I can hear dial tone for only a second and later there is a prompt saying "the person you have call is unavailable please leave a message after the beep", which mean it go to voicemail. From other side, the phone ringing for a second and then the voicemail lamp is blinking.

Call suppose to go to one ring group and I have configured the ring time is for 60 seconds. All extension members in the ring group is online.

Is there anywhere I should check regarding this issue?

Hi @Shahril

More info please, where are you calling from and where are you calling to?

From a 3CX PBX to another 3CX PBX?

Describe your call flow entirely, with as much detail as you can

Hi Support

I am calling from 3CX PBX and mobile phone to another 3CX PBX. Both showing same outcome which is when we call the number, we only hear dial tone for a second and then the voicemail's voice prompt come.

We have configured 1 SIP trunk with 10 DID numbers to the system, most of the DID number can be reach, just several showing this issue.

When you call this DID from your mobile, what is the call flow in the destination PBX?

You said the DID is sent to a ring group correct? Change the DID destination to go to directly to an extension and tell us if it works this way
