good Morning,

the technical support of the Aastra Sip they told me, the problem is the ACK packet 4092:

The ACK (4092 package) is invalid. In particular, the Request-Line contains the following parameters:

Sip.instance + = "<urn: uuid: 00000000-0000-1000-8000-00085D37C118>"

The quotation marks ("), the greater than sign (>) and less than (<) are not allowed in the value of the parameter, according to RFC3261 (see http://tools.ietf.org/html/rfc3261 # section- 25.1)
