We are running a UC540 with 11x SPA504 phones. Of course QoS has been applied. Customers complain about the low level of volume of both incoming and outgoing calls. Is there a way to tune this audio level to better dB level?
Thanks in advance!
CCA MONITIOR Telephony--> Phones and Extensions, shows the running FW on each phone.
What SW version you running on UC540 and SPA504 phones?
The latest release did address volume issues with the phones (release notes).
