Hi list: I have an issue with a new Snom 821. I've configured valet_parking for auto park mode (eg: my_lot auto in). After the attended transfer, I always receive a Temporarily Unavailable response on the Snom phone from FS. This does not hold true on my yealink/cisco/linksys/etc phones. I can do proper attended transfers from extension to extension on the Snom. I've tried this on a separate machine with latest stable, and latest git head. Dialplan: <extension name="valet_auto_park_in" > <condition field="destination_number" expression="^(7900)$" > <action application="valet_park" data="my_lot@${domain_name} auto in 7901 7999" /> </condition> </extension> <extension name="valet_auto_park_out" > <condition field="destination_number" expression="^(79\d\d)$" > <action application="answer" /> <action application="valet_park" data="my_lot@${domain_name} $1" /> </condition> </extension> screenshot from wireshark: http://tinypic.com/r/jtp5hc/5 Relevant Log: http://pastebin.freeswitch.org/21322 Snom Firmware Version: snom821-SIP 8.7.3.19 The call flow analysis on wireshark doesn't include any of the sip messages that follow the 480, so it doesn't really provide much there. Any pointers would be greatly appreciated. Duplication (for my own personal sanity) would also be appreciated. Could be I just got a bad phone... Regards, James PS: I know the timestamps on the wireshark don't match the log. They are from different tests, but the results are always the same.
