[Asterisk-Users] Polycom Call Park (with sip debug attached)

[Kristian Kielhofner]

If I have two extensions:

exten 128 SIP username: chris
exten 117 SIP username: pam

I call 128 from 117, and then try to use the Polycom IP 600 "park" 
softkey (on 117), it fails and this is what happens:

It looks like in the first park request, * barfs on "Refer-To: 
sip:callpark at pbx.kcdemo.com;orbit=401"  This makes sense, because after 
pressing park I was prompted for what looked to be a park position, 
where I entered 401 (the first position in features.conf).  Is there 
anyone out there that has experience with this?  I have found some stuff 
from the archives but it doesn't help much.  Ideally I would like the 
park button to park the call on the first available position and go 
straight into a page, which I have already worked out with these phones. 
  Will SuperValetParking or any of the other alternative apps help with 
this?

Thanks.
