[asterisk-users] duplicate "ghost" calls with long duration

[Bjoern Metzdorf]

Hello everybody,

I am running 1.2.10-BRIstuffed-0.3.0-PRE-1s with florz-patches on Linux 
2.6.16 with 4 HFC-Cards in TE-mode connected to 4 PtP 
ISDN-"Anlagenanschluesse". There are about 40 SIP-clients connected 
(mostly Sipura/Linksys PAP2, and some SNOMs and softclients) to this server.

Everything works fine, except that my CDR reports some very long 
_concurrent_ calls from one sip client to (an expensive) pstn 
destination. The CDR from my telco tells the same!

First case:

Sep. 05 2006 11:46:40 20 secs call from X to 0900xxx (valid call, 
micropayment)
Sep. 05 2006 11:52:18 3573 secs call from same X to 0900xxx (????)
Sep. 05 2006 11:53:24 3466 secs call from same X to 0900xxx (????)

X is a Sipura-connected hardphone. The guy swears he has only done the 
first call. Strangely the others are concurrent and to the same 
micropayment number, which itself disconnects callers after the 
micropayment value has been reached!

Second case:

Sep. 21 2006 14:30:22 35981(!) secs call from Y to 01805xxx (????)
Sep. 21 2006 14:31:00 1823 secs call from Z to 01805xxx (valid, 
conference provider call)
Sep. 21 2006 14:36:09 35634(!) secs call from Y to 01805xxx (????)

You see the valid call is made from a different caller, Z instead of Y. 
Y is also a sipura phone as well as Z. Y did never call this number itself.

Since my telco's (Deutsche Telekom) CDR tells me the same, this problem 
seems to be an asterisk internal one.

Any hints?

Regards,
Bjoern
