I've got several hanged VoIP calls on AS5300, timers ticking but there is no active connections on e1 line nor on other side gateway. This calls keep spamming AAA server and slow down active calls listing. How can i:
1. Clear that calls without rebooting AS
2. Setup peer with call timeout, so no single call may exist for over than 30 min, for example?
I do not use any gatekeeper software.

For the command clear call, you these option some them may help you.
clear call voice causecode 1 ?
called-number clear only call with specific called number pattern
calling-number clear only call with specific calling number pattern
id clear only call with specific id
long-dur-call clear only call with long-duration being detected and notified
media-inactive clear only call with media inactive being detected and notified

clear interface serialX:Y where X is the PRI number and Y is the channel.
Bear in mind, that dorpping channel 15 will drop all calls on the given PRI!
with calltracker
(1st you have to enable it and use something like: show call calltracker active | include calling).
If you found the channel, you can use:
e.g.: (with calltracker)
DS0 slot/port/ds1/chan=0/1/1/13, called=, calling=(n/a)
clear int s1:13

Clear interface serialX:Y will NOT work, because the only thing hanging is DSP. Look this sample output (as5350, 12.3(16a)):
b5-c5350-voip5#show voice call stat | i 2/4:D.1
0x4E9B E44 0x64980238 2/4:D.1 3016/5 8228100324 g729r8 7893737/6008

As you might see, all three calls reside on the same port.
Timeslot could be free or occupied by another call. There could be no opened TCP and UDP sockets related to the first call. Just a busy DSP. No known workaround yet, unfortunately.

You have a point, but can you explain me a little bit more? I know a DSP is a physical module on the voice board. With a G.729 codec - 8 kbps,you have two voice channels encoded per DSP.
The question is: how is the DSP busy ? Not the voice channel is busy ?
You say the voice channels are free or busy with new calls, but the DSP is busy from this bug, feature or whatewer, which is keeping the call alive and is messing up the billing...

Well, the original post was about as5300, but as5350's have similar problem and I believe that problems have a common root.
Lets look closer:
router#show voice call status | i 2/4:D.1|Port
CallID CID ccVdb Port DSP/Ch Called # Codec Dial-peers
0x4E9B E44 0x64980238 2/4:D.1 3016/5 8228100324 g729r8 7893737/6008
Substring "3016/5" shows that 5th channel on spe 3/16 is dead.
router#show spe | include 3/16|Port
SPE SPE SPE SPE Port Call
SPE# Port # State Busyout Shut Crash State Type
3/16 0096-0101 ACTIVE 0 0 0 _____a ______
Notice, that Port State is "a" (active), but corresponding Call Type is empty. Not "v" (voice), not "f" (fax), just empty.
You may shut/no shut that particular spe, mark it as "busyout" or upgrade its firmware, but all these actions won't help. Port State "a" appears again for the same channel and as5350 marks that channel as "In-Use".
router#sh spe | i Total
Ports : Total 120 In-use 35 Free 85 Disabled 0
router#sh isdn stat | i Total
Total Allocated ISDN CCBs = 32
See the difference between ports "in-use" and isdn ccbs. There are three dead ports.

Sorry, I reloaded all my as5300's last night, so there are no dead DSPs.
Try to compare the first "Inuse channels" field from
router#show call resource voice stat | i Inuse|Stat
Resource Monitor - Dial-up Resource Statistics Information:
DSP Statistics:
Inuse channels: 0
DS0 Statistics:
Inuse channels: 0
and
router#show isdn stat | i Total
Total Allocated ISDN CCBs = 0
