Hi Jon,

Thank you for your report and help. The fixes are available on git, so if you update you should be able to get the right behavior.

Best regards,

Hi Jon,

Could you (off list) provide the content of your dr_gateways and the value of the AVP, so I can run some tests on my side ? And of course, the exact OpenSIPS revision.

Thanks,

Hi Bogdan,


Thanks for the reply!


Yes correct the $avp(originURI) I set to;


$avp(originURI) = "sip:" + $si + ":" + $sp;


Then use it a few times;


if(dr_is_gw("$avp(originURI)","1")) {

####Do some stuff

}


if(dr_is_gw("$avp(originURI)", "2")) {

##### Do some other stuff

}


However since the upgrade from 2.2.5 to 2.3.2  $avp(originURI) which as you say is coming from FS, and is in type 2, is actually matching on dr_is_gw("$avp(originURI)","1"), as well as dr_is_gw("$avp(originURI)","2").


Where type 1 is just SBC and has always been.


So it doesnt fail on a look up on 2, but matches on a lookup of 1.


I have tried changing the type number but still same.


Thanks


Jon

Hi Jon,

So, the $avp(originURI) holds a SIP URI pointing to a FS box. But the check against group 2 fails and against group 1 succeeds ?

Hi Guys,

Is there any reason why after moving from version 2.2.5 to 2.3.2 that I would then get issues with drouting module, in particular dr_is_gw ?

As if I test between the two versions the same statement doesnt match correctly.

Essentially I have 2 main gateways types in dr_gateways, type=1 for our SBC and type=2 for our freeswitch servers.

I normally match using dr_is_gw to determine if traffic is from SBC or FreeSWITCH, however this now no longer works and on the first occurrence of me writing this statement;

if(dr_is_gw("$avp(originURI)","1"))

Where $avp(originURI) = source IP of freeswitch type=2, opensips keeps stating its from the SBC, type=1.

This only happens after upgrade, so works fine with 2.2

Has this function changed between versions? Has anyone else had this issue where its matching the source IP against the wrong type?

Please let me know if I need to change the syntax I am adding to the function!

Many thanks

Jon
