Matrix Telecom Proton 308 - Barge-In

20 PROTON 206/308 V1 System Manual
• If the system detects ring back tone, it gives ring on your station. When you lift the handset, you get
connected with the desired party.
• The system uses the same trunk type you used to make a call. If you dialed the number using trunk access
code 5, the system takes one of the free trunks from this group for Auto Redial. If you tried out the number on
a selected trunk, the system uses that particular trunk only.
• Auto Redial will suspend if there is any activity (ringing or dialing) on your station. It resumes as soon as your
station becomes free.
• Auto Redial does not work in following cases:
• If the trunk lines do not support standard tones. Frequency and timings are critical for auto redial to work.
• Trunk condition is poor and various tones cannot be detected properly.
• Called party lifts within 3 seconds after the ring starts on his phone.
• Behind the PBX applications where Matrix trunks are connected to stations of some other PBX which do not
support standard tones.

Barge-In
What’s this?
• When your message is urgent and you cannot wait for the called person to become free, you can land in his
conversation after intimating him.
• While landing, you get music and the called person gets beeps of internal call waiting tone.
• During the beeps, the called person can dial ‘Flash-1’ to answer your call. In this case the third party is put on
hold and gets music and hence cannot listen to your conversation.
• If the called person does not dial ‘Flash-1’ then speech is automatically established after time = barge-in
timer.
• Replace your handset once your talk is over. This will automatically restore his original speech with the held-
up party.
How to use it?
Example:
Station 23 is busy. To give a very urgent message to him, dial 33 on busy tone.
