Hello,<br />
On the gateway T-1 PRI under Product Specific Configuration the settings for Input Gain (-6..14 db)* and Output Attenuation (-6..14 db)*<br />
<br />
I have several users complaining of echo and that they have a hard time hearing the other party on the phone.<br />
<br />
Currently I have the Input Gain set at 5 and Output Attenuation at 9.<br />
<br />
If &nbsp;I need to increase the ear piece volume so the user can hear the other party which one should be adjusted? And which way? Negative or positive.<br />
<br />
Also to remove the echo (which isn’t constant or very much) does anyone have a set of settings that worked for them?<br />

Hello,
On the gateway T-1 PRI under Product Specific Configuration the settings for Input Gain (-6..14 db)* and Output Attenuation (-6..14 db)*

I have several users complaining of echo and that they have a hard time hearing the other party on the phone.

Currently I have the Input Gain set at 5 and Output Attenuation at 9.

If  I need to increase the ear piece volume so the user can hear the other party which one should be adjusted? And which way? Negative or positive.

Also to remove the echo (which isn’t constant or very much) does anyone have a set of settings that worked for them?


Input Gain/Output Attenuation

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
