Web Client Dual ring tone

[Markus Ray]

Since the V18 upgrade users are having an issues where calls made from the web client(for their GXP2170 handsets) are playing a double dial tone(one regular dial tone and one ringing). It still functions properly once the call is picked up but the dial tone playing at the same time as the ringing is throwing users off and causing them to think it is not working.

I found a thread that seems to be referencing the same issue but it doesn't look like it ever got solved.

Any chance anyone has come across this issue and has some suggestions on how to resolve it?

Hi @Markus Ray,

A few details. Is the phone local to the PBX? Are they using the Web Client with the GXP2170 in CTI mode?

Phone is on a local network connected to our cloud hosted instance via a local SBC. It seems to happen anytime a call is initiated from the web client for their GXP2170(using CTI). And it only started after we recently updated to 18.0 (Build 1880).

We have had this reported before some months ago and strangely enough, it seems to only happen when the call is initiated via the WebClient (CTI/CSTA).

We in turn have reported this to Grandstream as it seems to be an issue in the firmware, but ave not received feedback that it has been fixed. Last firmware we checked that this issue was present on is 1.0.11.35.
