Soft call both end

[Sumit Bharti]

Hi All,

client has been complaining about the soft call on both side, basically its really hard to hear the other party on the phone.
Can someone help me to advise me what can be done to improve the audio quaility.
We have been using PCMA a top codec for Extensions. Phones are all Yealink T57W.

Thanks

Hi,
is it on all kind of calls internal / external?

What is the audio codec expected by yuor sip provider?

is it on all phones on PBX or only one T57W?

do you set up volume on phones?

Hi Sumit,

Have the user dial *777 (echo test) to hear their own voice.

While in call increase the volume of the handset and see if this improves the situation.
