Can't receive SMS messages with an alphanumeric sender in v18 Update 8

[LawrenceF]

We upgraded our PBX to v18 Update 8 last week but since then we have not been able to receive any SMS messages that have an alphanumeric sender ID through our Telnyx trunk.

SMS messages that have a standard mobile number sender ID received at the same DID come through fine to the same destination (a queue in 3CX).

The chat logs in the 3CX management console also show nothing received for alphanumeric sender IDs since the upgrade to Update 8, but the test messages I sent from my own mobile are shown.

The Telnyx reports show that the SMS messages, both with standard mobile number sender IDs and alphanumeric sender IDs, were received at their end and were successfully delivered to the 3CX webhook.

Anyone else seen the same issue?

Yes, we cannot receive any text's from Alphanumeric senders. Checking the 3CX logs we can see this error: Received request with invalid 'from' address: 'Alphanumeric'

Yes, we can confirm this is an issue - we will work to address it. The message is received just not displayed.
