Hello,

I am having a problem retrieving parked inbound calls  at sipxpark  (
see http://track.sipfoundry.org/browse/XECS-1726 ).



I have attached the snapshot here :

http://track.sipfoundry.org/secure/attachment/16746/sipx-configuration-sipxtest.example.local.tar.gz

Here is the merged.xml for the interaction of interest:

http://track.sipfoundry.org/secure/attachment/16747/merged.xml.gz

The Scenario is :

1. The inbound call arrives from an ITSP.  It is answered by extension 203
2. 203 parks the call ( REFER to extension 300 )
3. 201 attempts to retrieve the call.

The retrieval does not work.

In the merged.xml above :

Notice the NOTIFY on Frame 166. This matches the REFER dialog but the
Park server is rejecting it with a 481.


The tags for NOTIFY look fine it as far as I can tell.  I looked
through the park server log files and it appears that the reason for
the failure is that the NOTIFY does not have a Proxy-Authorization
header. Indeed sipxbridge does not get challenged for
Proxy-Authorization and hence the NOTIFY cannot have such a header.
The Park server consequently never hangs up the call with the inbound
caller on park ( never sends BYE). At least, that is my best
conjecture.

I request a park server expert to look at the snapshot and the
merged.xml file above for this scenario and please let me know if this
is the problem ( as I suspect it is ). If so then, how do I get around
this? Can the park server recognize that a trunked call is being
parked and be kind and not send 481 if Proxy-Authorization is not
present?

Thank you in advance for any help.

Regards,

Ranga
