Problems with CCM 4.2(3)

When i try to call from ip phone->ip phone or ip phone -> PSTN (PRI), every thing is ok, but when i hung up again the phone the number still blocked in the phone and i had no tonality, is during blocked (may be 20 sec).

Note: CCM version 4.2(3)

OS version: 2000.4.3a

ip phones 7911 and 7960

CCM configured with MGCP gateway 2811, and i've PRI E1

Thanks is very urgent.


Re: Problems with CCM 4.2(3)

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?
