Dear All,

In my telecom network we are finding huge call drop (15 calls drop per day), cracking noise on calls and blank calls(customer not able to hear and some times agent not able to hear customer).Requesting you all to provide me the technical tips to over come the problem.

Bharath,

The bit of string is drying out between the two tin cans :-)

Seriously though:-

What switch?
Analogue, Digi or VOIP?
Lines per card?
What % of your call volume is this?
How many agents logged on at the time? Peak?
Occupancy Vs Capacity ratio. (Switch not desks)
Trafic volume at time Vs Capacity

Anything we add at this point would be guesswork.

First thought if VOIP is poor compression

or

If Digital, a partial card failure in the switch but....

It's just that, guesswork.

What switch? ----S8720
Analogue, Digi or VOIP? -------VOIP
Lines per card? ------- DS1 card for 23 channels Thz T1
What % of your call volume is this? ------- 7000 per day
How many agents logged on at the time? Peak? -------150 in peak 250
Occupancy Vs Capacity ratio. (Switch not desks)
Trafic volume at time Vs Capacity

Judging by how infrequently it happens...yet consistently I would really look at VoIP and network congestion/compression as likely culprits.

I'd also suggest you try tracking these calls and what their symptoms are, there may be a pattern you aren't seeing.

I personally wouldn't describe a 0.21% drop rate
as huge!

This could even be down to inadvertant hangup's

It's actually a 1:476 ratio.

I think you're chasing a ghost!

Customer end rather than system or at absolute
worst case 'finger trouble' with 1-2 agents.

Good luck.
