I will say this.. I'm running 4.2.3 with an MGCP gateway and do not experience this problem. So If I heard you right, you call hang up and pick up the phone to dial anther number, but you get no dial tone. If so, how many phones experience this problem. Go ahead and upgrade to OS version 2000.4.4 with latest SR. What firmware is on the phones?

hi kelvin, thanks for your answer.

you are right. I have 50 IP phons in the site, and all the IP phon have the same problem. I had the version 2000.4.3a and yesterday I maked an update to the 2000.4.3aSR8 but I always have the problem.

For the firmware of the IP phons:

7911: 8.0(4)SR2
