[asterisk-users] Parked calls drop asterisk-1.4.22.1

[das sandesh]

Hi

We are facing a problem for orphaned parked calls, we have the following
config:
asterisk -1.4.22.1
dahdi-linux-complete-2.2.0.2+2.2.0

and when we get an incoming call and after it gets parked, after some set
time (here its 2 min), it goes back to the operator, but the problem is that
randomly it tries to call SIP/5060 instead of SIP/2200 (where 2200 is the
extension number of the operator) and we get the error as "Unable to create
the channel of type SIP (cause code 20)" and then the call drops, we even
tried asterisk-1.4.23.2, but in that version we were having problems with
paging/intercom using the phones.

[Oct 19 11:55:28] VERBOSE[2996] logger.c:   == Timeout for SIP/5060-b781fe80
parked on 71. Returning to park-dial,SIP/5060,1
[Oct 19 11:55:28] VERBOSE[14641] logger.c:     -- Executing
[SIP/5060 at park-dial:1] Dial("SIP/5060-b781fe80", "SIP/5060|30|t") in new
stack
[Oct 19 11:55:28] WARNING[14641] app_dial.c: Unable to create channel of
type 'SIP' (cause 20 - Unknown)
[Oct 19 11:55:28] VERBOSE[14641] logger.c:   == Everyone is busy/congested
at this time (1:0/0/1)
[Oct 19 11:55:28] VERBOSE[14641] logger.c:   == Auto fallthrough, channel
'SIP/5060-b781fe80' status is 'CHANUNAVAIL'

We also have the option of "Page/Intercom" through the phones that auto
answer.

Can any one share any ideas or opinions?

Thank you,
Sandesh
