Phone A can reach Phone B, but Phone B cannot reach Phone A
Hello,

I am using a grandstream UCM 6208 with 4 yealink T43U phones.

The 4 phones are configured the same way, but I have a problem with 2 of them.

Telephone A and B
Phone A can reach Phone B, but Phone B cannot reach Phone A.

Do you have an idea ?
Thanks

Hi,

If all 4 phones are configured the same way, I think you should troubleshoot the Grandstream PBX.

Kind regards,
Frank.

I made the same post on the Grandstream Forum and they tell me that the problem comes from the phone.

RE: Phone A can reach Phone B, but Phone B cannot reach Phone A
Hello,
On my phones, I have a "warning icon" and I don't say why. I check the icon for my T43U, but I don't see that icon.
Have you an idea ?
Is that a sign that there's something wrong?
Thanks,

Hi,

The warning icon may indicate that the device is not properly provisioned and/or the default username/password (admin/admin) is still being used.

Kind regards,
Frank.
