Tony,
I do not have access to the device but in the INVITE it contains a header of Server: Patton SN4940 1E24V .R5.T 2011-01-17 . SIP Stack/4.0.30.30 However, I don't think it is an issue with the gateway because I would have thought that in the REFER from the park server to extension, the Refer To: should have been the original Contact of the parked caller from the Patton gateway, however it contains the contact for extension 202. That does not seem correct to me.

The call was inbound from a Patton gateway and was answered on extension 202. That person parked the call on extension 220. When they attempted to pick-up the parked call using *4220, the attempt ended in a fat busy. The attached file contains a trace of the call flow of the pickup attempt of the call from park extension 220 by extension 202 who had parked the call. The message sequence looks fine until the REFER is sent back to the phone provisioned with extension 202. At frame 34, the Polycom phone issues an INVITE with no SDP. I believe that is to signify that the park server should stop MoH and prepare to transfer the call. However, what we see is a series of INVITEs where sipXproxy is sending the INVITE to itself and sipregistrar and ends up with the proxy issuing 482 Loop Detected and 483 Too Many Hops. Could someone please tell me what is wrong with the pickup sequence or the INVITE at frame 34 from the Polycom phone that would send the flow into a "tail spin"? This is an intermittent issue as the vast majority of attempts to pick-up a parked call works on this system.
