We have several units of the GXP2160.
The thing is, they’ve been working fine until a couple of months ago. Probably after some firmware updates.
The error is that, when the operator is answering a call with the handset and another call comes in, the phone activates the handsfree and both the ringing that sounds in the operator’s speaker and the ambient noise is heard by the caller of the first call which is quite annoying. It is a kind of handsfree loop.
The operator does not touch any keys to make this happen. The configuration remains the same as it was when they were installed and has worked well for almost a year.
When we noticed the error, the phone had version 184.108.40.206 installed. To see if it was fixed, I installed version 220.127.116.11 but it didn’t work. We had 18.104.22.168 installed before, but I can’t tell if we didn’t already have the problem with this version.
Of course, I have checked the call features values and everything seems to be correct…
After upgrading, I also tried to restore one of the phones to factory settings and reconfigure it from scratch, but it didn’t work either. This is the only thing I have seen in the GrandStream forum for a similar case.
If anyone has any suggestions, I’d be happy to try them out.
Thanks in advance.
