Office Communication Server 2007 R2 (OCS 2007 R2) with SPA2102

Hello,

I’m trying to use a Linksys SPA2102 with Office Communication Server 2007 R2 (OCS 2007 R2). My configuration: I’m using a PSTN Box (Ferrari Gateway) to connect ISDN to SIP.

1.       All incoming Calls over ISDN go to the PSTN Box

2.       From the PSTN to Microsoft Mediation Server (SIP)

3.       And from Mediation Server to an OCS Server (SIP)

4.       And from the OCS Server to my Clients. (SIP)

So I’m trying to use the SPA2102 as a Client at this network, to get a Fax via SIP end send the Fax to my “old” Fax via the Line 1. So the SPA2102 is planned to use as a “Bridge” to go back from incoming SIP to the “old world”. I tried to configure the Line 1 with all OCS credentials but it didn’t works. I could figure out with the Cisco support and Microsoft, that both System cannot understand each other:

ms-diagnostics: 1018;reason="Parsing failure";source="XXX-06.XXX.local"

So the question is, is there any possibility to configure the Linksys SPA2102 to communicate correctly with OCS 2007 or did you ever have made an installation with OCS 2007?
