Hi,
As I noticed the message, the problem lies in the message from the IP
phone A. If you could see the INVITE message from IP phone A, it has "ROUTE"
header, but in case of INVITE message from Cisco, there is no "ROUTE"
header. Both the SIP phones will forward the request to the pre-configured
route and in first case, Pulver again forwards the request to the top route
which is of its own and hence the problem.
Messages that you sent,
