calling. Also if the called extension has set Privacy from Do Not Disturb (DND) - Override, then ETERNITY will
reject the Intercom call initiated by you. You can check the topics Priority and Intercom in the chapter Features and
Facilities from the ETERNITY System Manual.
Q. I cannot access Interrupt Request (IR) from my phone although it is allowed to me.
A. Interrupt Request will work only if the called party is in a normal 2-way speech with some other extension user or
an external party. If the extension is busy due to being Off-hook (for example, Handset is not placed on the cradle
properly) or in the middle of dialing or accessing some ETERNITY feature, then you will not be able to access
Interrupt Request.
Q. Some entries in the Call Logs list are displayed as ‘Unknown’.
A. Entries in the Call Logs list are displayed as ‘Unknown’, if the ETERNITY is unable to detect the Number (CLI)
associated with them. There can be multiple reasons for which this can happen; for example, due to mismatch in
Calling Line Identification (CLI) format configured on the CO trunk of the ETERNITY with that of the service
provider/exchange. You cannot place calls by tapping Unknown entries.
SPARSH VP510
Q. I get the message ‘A network cable is unplugged’ on the screen.
A. This message is displayed when the Ethernet cable is unplugged from the LAN port. If you are connected to the
network using the Ethernet cable, you will not be able to make/receive calls or access any phone features. Ongoing
calls will be disconnected.
Q. I get the message ‘IP Address conflicted with MAC Address “XX:XX:XX:XX:XX:XX” on the screen.
A. This message is displayed when the IP Address assigned to the phone conflicts in the network. Change the IP
Address of the phone or contact your System Administrator to resolve the conflict.
Q. I cannot access Live Call Screening, Background Music, from my phone.
A. SPARSH VP510 does not support the Live Call Screening, Background Music feature.
Q. If there is an incoming call on a trunk for me, I do not get any indication.
A. SPARSH VP510 does not support the CO Call Waiting (or, Trunk Call Waiting) feature even if it is enabled in the
Class of Service assigned to your extension. So if there is an incoming call on a trunk for the SPARSH VP510, then
you will not get any trunk call waiting indication.
Troubleshooting Tips
Problem/Symptom
Probable Reason(s)
Alarm cannot be set.
Maximum number of Alarms supported by the
ETERNITY have already been set. So new alarms can
be added only after deleting the old ones.
Beeps are played in an established call and after
sometimes the call gets disconnected.
Call Duration Control (CDC) may be enabled in the
ETERNITY. Ask your System Administrator for
assistance.
