CS1K R5 SIP Redirect Service

[Arriero]

Good day all,

I hope you can give me some light on this problem.

The call scenario is as follows:

Node A:
CS1000E, CCPM, R500W + SS CCPM R5.00.31
SS TLAN IP: 172.25.15.20
Node IP: 172.25.15.50
SS Apps: SIP GW, H323GW, NRS (Primary)
Calling DN: 84177

Node B:
Static SIP Endpoint
IP: 172.25.15.60
Called DN: 83900

The call does not complete and I get fast busy on the phone.

When I trace the call on the SS, this is what I get:

oam> SIPCallTrace: (02/06/10 16:55:26) This is Outgoing Message
SIPCallTrace: (02/06/10 16:55:26)

02/06/2010 16:55:26 LOG0006 tSPMsg: MPLR27605: spOsipEventHandle: lineno 1516, duplicate event found.


After the 302 Moved Temporarily Message I was expecting to see something like this:

Contact: <sip:83900;phone-context=cdp.udp@servicedomain.com:5060;maddr=172.25.15.60;transport=udp;user=phone;x-nt-redirect=redirect-server>

However that line never shows and there are no more SIP Messages after the ACK(1)

If I run a SIP Routing Test to DN 83900 in the NRS, then I get the correct information, the tool points to 172.25.15.60 which is the static SIP Endpoint.

I guess the answer is in this message: 02/06/2010 16:55:26 LOG0006 tSPMsg: MPLR27605: spOsipEventHandle: lineno 1516, duplicate event found. But I don't know how to read it.

Any guidance is appreciated,

Thanks

Is 83xxx in the NRS?

Mike,

Yes 83xxx is a properly configured routing entry in the NRS. In fact if I do the SIP routing test to 83xxx I get the correct gateway endpoint.
