Good day,
we have a strange problem with a new 3CX installation.
90% of outgoing calls via Telekom are rejected
with the message: 488 Not Acceptable Here
Dialing the same number with the softclient and headset works,
you let the softclient dial the phone in CTI mode it does not work.
Not even if you dial directly via the Yealink T58A.
For a phone that is provisioned via stun-external it works
interestingly, but it doesn't work in the local LAN either.
In stun-external mode, the phone also works in a different mode than directly in the LAN.
We tried a second provider (Placetel), so we can get out without any problems.
Are there known incompatibilities between Yealink and Telekom?
Or can it be a problem because the T58 does not support G711?
Greeting unibeta
