My company probably have the same issues as stated in the above URL.
However, we have disabled all the ICMP redirect in routers, switches and even firewalls.
So why the problem still occur? Is there any other solution could be solved?

How many phones are doing it? What type of phones are they?
When it happens, does the phone go through a countdown sequence?

check your software level. I beleive a combination of turning off ICMP redirects & upgrade to MCD 4 SP3 cured our issues.

Ah the lovely ICMP redirect issue. We found the issue after calling for an incredibly varied amount of times ended up being the management module in our clients HP switches this was found through wireshark captures from phone to phone.

Actually we are working around 120 phones with around 60 VOIP phones and 60 Digital phones.
The models are Telset Model 5212 & 5312 (For IP phones), 4015 & 4025 (for Digital phones).
It happens in random time! Almost 2 - 3 phones would drop their call unexpected everyday.
For the countdown sequence, would you mind to explain further on it as I am fresh to Mitel phone system? :-\
Many Thanks!

I'm assuming that the problem only happens with the IP (53xx) phones.
A count down sequence is when on the display of the phone you see it counting downwards from about 10 to 1.
It would go
"10"
"9"
"8"
..
"2"
"1"

I would suggest to setup a computer or something behind two of the more problem children ie the two people that talk the most and do a wireshark I can almost bet you will see an ICMP redirect. Obviously you will not be able to capture a digital device. This is how we found our with 5312s and 5324s.
