The issue is back, and i need to figure this out, hopefully someone has found a fix. I dont know what other settings i can change to prevent this. Two dialers Different dial plans. Different ISPS different VOIP providers.
I would like to know if some of the people who had this issue in the past, if the issue went away with vicidial7 (asterisk 11)


chan_sip.c:4058 __sip_autodestruct: Autodestruct on dialog '236b4eb2638f37063d4c8a8450ad6d21@108.9.141.70:5060' with owner SIP/ IPLINK1-00005d95 in place (Method: BYE). Rescheduling destruction for 10000 ms

At times getting the RTP at 61 seconds error as well.

when i did sip show channels. This is what i seen

Fixes i have attempted. I added () to the end of the dial plan after hangup, and it seemed to slow it down. The systems have been restarted every night. The big issue is it is causes a lot of extra money to be spent on VOIP, i really need to get some help on this one. The channels are stuck open even when they do not go to agents, so please advice on how to shut down these channels or how to fix the issue. The ISP speeds are also fine. ONe of the systems having this issue only has 5 agents and is 35/35 MBPS. I also made sure that Asterisk version was correct. in vici. I am at a loss, i know others have had this issue. so hopefully i can get a answer that will work for me this time.

Dialer One DIal plan

[IPLINK1]
type=peer
host=XXX.XXX.XXX.XXXX (carrier ip is correct, but do not like posting IPs)
canreinvite=no
qualify=yes
disallow=all
allow=ulaw,alaw
dtmfmode=rfc2833
context=trunkinbound

exten => _9COC1NXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _9COC1NXXNXXXXXX,n,Dial(SIP/IPLINK1/${EXTEN:4},,tTor)
exten => _9COC1NXXNXXXXXX,n,Hangup()

Dialer 2 Dail plan

[Xcast]
insecure=port,invite
secret=no
qualify=yes

disallow=all
allow=ulaw,alaw,g729

If you need any more information just ask here or in private, This has to get resolved.

Also i know this is in asterisk, has anyone had this issue, then upgraded to asterisk 11 and the issue go away?

I had the same issue. What is ur max trunk and max call per second value?

I set my servers to reboot nightly which kinda help. I always thought that this is an asterisk issue but i believe it is not

I think it might of been. Was you running 1.8?

I just said screw it, and upgraded them to vicibox 7 with asterisk 11, I will know in a week or so if it is still a issue, because it comes on about a week after install. Kind of sucks, because it is hard to trouble shoot after a reinstall

Max trunk is set a 200
max call at 20

I had the issue, did the nightly restarts, but once the issue hit, it would not go away, and the autodestruct would go completely crazy and i knew there was a issue. Just for the future, if i may need to know, what ever steps did you take to resolve it.

But if everything is good in a week, i will know it was a some kind of bug in 1.8.

You shouldnt set ur max trunk like that. It should be around 95 based from
Mu settings. And call is somewhat same value. I change mine to that value and it works now.

Yep i am running 1.8. I had same thinking just like u do before but when i read a thread here and change those settings and it just works

If you are using SIP your Max Calls per Second should be much lower than 20. I would try setting it to 4.

I've had clients who had to set their (press one dialer) max calls per second to over 100 to maintain the dial level they needed. Depends a LOT on the carrier. But I've never had a client with "stuck" calls even with high max calls per second unless they were simply overloading their server.

I will say that the poweredge 1850 is a wee bit old and 4 cores total is a wee bit small. But if you're staying under 200 calls on the server you should not really be in overload.

However: You did not post any aggregate data on the occurrences. I'd suggest you begin tallying information about what these calls and "occurrences" may have in common. You may find a report getting run that overloads sql and stops an agi script from completing on a bunch of calls at regular intervals or the same time of day. If you're lucky. 8-)

If you're even luckier, asterisk 11 will solve it. But a bigger server may also be your solution. Eight cores is better than 4.

Went with a more powerful system and went to 11, have not seen the issue, also told people to keep the max call per second at 4 just to be on the safe side. I have not had any issues yet, after two more weeks, i will visit this topic again in about a week and if all is resolved i will go through all the steps i took.
