Yes, up until recently I only had one install of same that I did in July of '20. Very little issue with them since, but no fancy stuff done and certainly no F/W upgrades since.
However, recently I have a client who insisted on them for a number of sites partly due to variois product shortages as they had been using a different PBX and phone make and wanted to stay as close as possible to the functionality of the other phones due to the added paged BLF buttons.
I have installed over 8 systems in the past 3 weeks and the service calls from same have exceeded all other clients combined over the same time and all for the GRP.
I understand that there may be some issues that require some firmware tweaks, but I simply cannot get over the fact that this thread, whose title expresses it all, dates back to May and here we are over 4 months later still waiting on a fix for a problem that never should have been an issue given how prevalent the need and use of ringtones are and since when should a phone quite ringing under any circumstance? In my case, I am using the 63XX, so even more concerning as it GS’s own product line.
I just obtained a dev F/W version from support that, per your suggestion (Thanks! and for the work put in) that reportedly addresses the ring issue. I just installed it into 5 systems with a few more to go and I guess we will see if it addresses the ring issue and then see what else it manages to break (hopefully not).
