We're seeing a strange behavior with our Gigaset DExx and N510/S510H phones, too: When someone using one of the S510 mobiles wants to transfer the call to another mobile using the "R" key, the new attendee gets displayed the transferor's id first and after the transferor hangs up, the display on the new attendee's mobile switches and now displays the original caller id -> Exactly like we want it. Now, when someone transfers a call using a mobile or one of the DExx desk phones to another DExx
, those desk phones display the transferor's id and after the transferor hangs up, there is a quick flash on the display, but the caller id stays the same and does NOT switch to the original caller id -> BAD.We also tried the **EXTEN feature for attended transfers, but this is not an option: The new call attendee gets displayed the caller id of the original caller immediately, although he first speaks with the transferor until the transferor hangs up. This is extremely confusing as nobody could trust the displayed info any more...
"Send Remote-Party-ID" = PAI has been set for all extensions and in the attributes box I tried this (again for all extensions):
Nothing works. In the DExx phone configuration, I set up PAI, too, as explained here: https://teamwork.gigaset.com/gigawiki/display/GPPPO/FAQ+Caller+ID
Our DECT bases and all the desk phones are on the latest available firmware.
I tend to think this is an issue of the DExx series, but isn't there a workaround?!
