I remarked or better said my customer remarked that it takes a little time (about 2-3 seconds) when he gets a call at his SMT-i 5343 from another SMT-i 5343 before he can hear the caller. I had testet it and my customer is right. I call with my SMT-i 5343 another SMT-i 5343, he picked up the handset, hold it to the ear and 1 second later he could hear me.
The System is a OS7400 Firmware 4.92 and the phones have Firmware 1.41.

Has anybody also remarked this Problem and what about a solution ???
Many thanks.
