Q. How to remove the buzzing or humming noise during the call?
A. Usually if the grounding environment is not properly installed, it will bring more noise or AC interference (50/60 Hz noise or line frequency hum) with the device. Thus, it is recommended to check if the grounding wire is connected properly. You can perform the following procedures:- Avoided sharing of AC power outlet with other devices (as this may generate electrical interference).
- Check if the rack is earth grounded properly.
- Isolate the equipment from the rack.
- Cut off the ground pin on the power plug.
Q. What can I do if I can hear a sound like a DTMF tone during the call without even pressing any key on the keypad?
A. Background noise disturbance will generate the sound that can be pick up by the microphone on the handset. This issue is also common to hands-free device. In order to prevent the false detection of DTMF signal, you need to increase the DTMF actual detection threshold on the VoIP device by system configuration.If you are using OM20/OM50/OM80E/OM200G/OM500
Go to Advanced > DTMF, then input 32 or 48 on DTMF detection duration increment against talk-off field (The range must be 16 to 240 in multiples of 16).If you are using HX4E/MX8A/MX60E/MX120G
Go to Basic > System, then input 32 or 48 on the DTMF detection duration increment against talk-off field (The range must be 16 to 240 in multiples of 16).
Q. What can I do if the voice volume is too low (or high) on an extension during the call?
A. When the voice volume is too low (or high) on an analog extension side or internal party, you can increase (or decrease) the Gain to terminal parameter value by line configuration. Test several values higher (or lower) than default value=0 until you get the normal voice volume.If you are using HX4E/MX8A/MX60E/MX120G
Go to Line > Advanced, increase (or decrease) the Gain to terminal value.
If you are using OM20/OM50/OM80E/OM200G
Go to Extension > Analog > Advanced, increase (or decrease) the Gain to terminal value.
A. When the voice volume is too low (or high) on the other side or external party, you can increase (or decrease) the Gain to IP parameter value by line configuration. Test several values higher (or lower) than default value=0 until you get the normal voice volume.
If you are using HX4E/MX8A/MX60E/MX120G
Go to Line > Advanced, increase (or decrease) the Gain to IP value.If you are using OM20/OM50/OM80E/OM200G
Go to Extension > Analog > Advanced, increase (or decrease) the Gain to IP value.
Q. What can I do to reduce the echo that I heard during the call?
A. When the analog extension side or internal party has echo, you can decrease the Gain to terminal parameter value by line configuration. Test several values lower than default value=0 until you get the normal voice volume.If you are using HX4E/MX8A/MX60E/MX120G
Go to Line > Advanced, decrease the Gain to terminal value.If you are using OM20/OM50/OM80E/OM200G
Go to Extension > Analog > Advanced, decrease the Gain to terminal value.
A. When the other side or external party has echo, you can decrease the Gain to IP and Gain to PSTN parameter value by line and trunkconfiguration. Test several values lower than default value=0 until you get the normal voice volume.
If you are using HX4E/MX8A/MX60E/MX120G
Go to Line > Advanced, decrease the Gain to IP value.Go to Trunk > Advanced, decrease the Gain to PSTN value.
If you are using OM20/OM50/OM80E/OM200G
Go to Extension > Analog > Advanced, decrease the Gain to IP value.Go to Trunk > Analog trunk > Advanced, decrease the Gain to PSTN value.
Q. How can I eliminate the crosstalk on an analog extension? (Conversation on another extension is heard during a call)
A. Generally, crosstalk is caused by telephone line short-circuits. Check the connection line of the FXS port and remove the line fault.
Q. How can I remove echo and noise during the call?
A. To mitigate the echo and noise related issues, make sure that Echo cancellation is enabled and FXO impedance is complex. You can perform the following procedures:If you are using HX4E/MX8A
Go to Trunk > Feature, enable Echo cancellation.
Go to Trunk > Advanced, set Impedance as Complex.If still has this issue, you can try to configure the echo and noise related parameters
- ECHO_TAIL, ID =300. Value range is 1-300 (Adjust every 30ms. From our testing results, 30ms is the best value, so we can start from 30ms then increase the value if we want to adjustit)
- Input the xml command on the URL: https://x.x.x.x/xml?method=gw.config.set&id300=30.- ECHO_CANCEL_LEN, ID =66. Value range is 16-64 (Adjust every 16ms. From our testing results, 64ms is the best value, so we can start from 64ms then decrease the value if we want to adjust it.)
- Input the xml command on the URL: https://x.x.x.x/xml?method=gw.config.set&id66=64.
