“Here’s an update, by debug the information provided, our development team seems find the root cause out, and are doing some code changes to verify.
Once we verify patch would good fit for that affected long distance call scenario, will let you know. I ask team and hopefully we can add this fix onto the next release.”

Hopefully this code fix will make it into all of the S4B T4X series phones with the next firmware update.

Fingers crossed that it will be sooner than later. We've tested Polycom (CX, VVX), AudioCodes (440HD - currently using in production), and Yealink (T46G, T48G) and we prefer the Yealink for our VDI environment with S4B.

Was this issue ever resolved? I have the same issue only we use Centurylink SIP trunks. All other devices work (polycom cx600, Sangoma analog). The phone client seems to have an issue not honoring rfc2833
