[OpenSIPS-Users] dlg_validate_dialog Error, help

Wed Oct 10 17:43:05 CEST 2012

Hi, while i was making some test for my lab ( place on hold and retrive it )
i noticed on opensips's log the following error:

*ERROR:dialog:dlg_validate_dialog: failed to validate remote contact:
dlg=[sip:5100 at 172.16.52.51;transport=UDP;user=phone] ,
req=[sip:5100 at 172.16.52.51;user=phone] *

I cannot understand why i get it. 
There someone that can explain why? what's wrong?

here is the entire SIP log of call.
Thanks a lot
