dlg_validate_dialog Error, help

Spady#7
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@172.16.52.51;transport=UDP;user=phone] , req=[sip:5100@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

Re: dlg_validate_dialog Error, help

Vlad Paiu
Hello,

Just as the logs says, the remote Contact is not valid according to SIP
dialog point of view. At dialog establishment the Contact URI was
'sip:5100@172.16.52.51;transport=UDP;user=phone ' while the sequential
SIP message contained 'sip:5100@172.16.52.51;user=phone'.

Notice the removal of the transport=UDP parameter.

In such cases, you should use the fix_route_dialog() function exported
by the dialog module.

Regards,

Vlad Paiu

Hi Vlad, thanks for reply.

Re: dlg_validate_dialog Error, help

Vlad Paiu
Hello,

The validate_dialog() and fix_route_dialog() functions are not currently
allowed in branch_route.

But what are you trying to accomplish, more exactly ? The validation and
fixing functions are meant to work on sequential requests, where you
know the dialog end-points, so there is no need to call them on a
per-branch basis.

Re: dlg_validate_dialog Error, help

Spady#7
Hi Vlad. Ok now it's a bit clear.
What i am trying to do is to solve the following issue:

PBX<--->Opensips<---->Lync server

Opensips acts as UDP/TCP proxy. Call can go from PBX to LYNC and viceversa. The problem comes when from LYNC I put on hold the call. Everytime i get the following error, just after i press hold button on LYNC:

Oct 11 13:43:04 opensips /usr/local/opensips_proxy/sbin/opensips[9512]: ERROR:dialog:dlg_validate_dialog: failed to validate remote contact: dlg=[sip:5100@172.16.52.51;transport=UDP;user=phone] , req=[sip:5100@172.16.52.51;user=phone]

So I want to solve it!!

Now I tried to put " fix_route_dialog() " in sequential requestes but problem is still present. Maybe i did not understand where to put it or how to use it. Can you help me?

if (has_totag()) {
                # sequential request withing a dialog should
                # take the path determined by record-routing
                if (loose_route()) {
                       
                        # validate the sequential request against dialog
                        if ( $DLG_status!=NULL && !validate_dialog() ) {
                                xlog("In-Dialog $rm from $si (callid=$ci) is not valid according to dialog\n");
                                ## exit;
                        }
                       
                        if (is_method("BYE")) {
                                setflag(1); # do accounting ...
                                setflag(3); # ... even if the transaction fails
                        } else if (is_method("INVITE")) {
                                # even if in most of the cases is useless, do RR for
                                # re-INVITEs alos, as some buggy clients do change route set
                                # during the dialog.
                                record_route();
                                fix_route_dialog();
               
                        }



Thanks
