Re: [OpenSIPS-Users] [Re: Routing problem with Record-Route]

As the next destination should be 6.6.6.6, some stupid questions:


1) is 6.6.6.6 configured in domain module or as "alias" ?

2) have you check to loopback interface ? maybe the ACK is spiralingover there.

Also, try to reproduce the ACK case, but enable full debug in script forthe loose_route() function:

    if (is_method=="ACK") setdebug(6);

And post the output of opensips - this will give some clue on what it isdoing.

in opensips log, no error, just no forwarding to customer IPBX.
but tomorrow I'll test with other debug option.

Thanks

The 7.7.7.7 and 8.8.8.8 IPs are both from the same instance of opensips
(doing interface exchange) or there are 2 different SIP entities ?

Also, do you see any errors in the logs when the ACK is handled ?

Hi

Hi,

Please post the ACK message your opensips proxy gets, and also the
outbound ACK request (leaving your opensips) - Include also the net
layer info (like src ip and port) - feel free to masquerade the IPs,
but
do it consistently,

Hi,
do you think this may be the cause of my routing ACK problem ?

Hi,
loose route parameter lr , which can be present in sip or sips
Record-Route and Route URIs to indicate that the proxy server
identified
by the URI supports loose routing.


RFC 3261 explains the "lr" parameter as just ";lr", not lr=on. This
brokes
some UAs which add =on to the "lr".  opensips adds=on  to be
compatible
with these UAs


//Binan.

Exactly Opensips add lr=on and callee device transform it into
lr;r2=on.

my other devices (asterisk, avaya, etc ...) do not transform lr...

My Opensips version is version: opensips 1.6.4-2-tls (i386/freebsd)

what is the difference between lr=on and lr;r2=on ?

So OpenSIPS adds "lr=on" but the callee device transform it into a
"lr".....

What version of opensips are you

    using?

Hi Bogdan-Andrei,
Thank you for your response.

Yes I confirm in INVITE I have 2 RR with lr=on:

<sip:8.8.8.8;r2=on;lr=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>
<sip:8.8.8.9;r2=on;lr=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>

and in 200OK I have 1 RR with just lr:

    
<sip:8.8.8.8;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>,<sip:8.8.8.9;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>

and in ACK I have 2 Route with lr:

<sip:8.8.8.8;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>
<sip:8.8.8.9;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>

Hi Mickael,

Can you confirm (for the failed call) that OpenSIPS added in
INVITE
RR
hdrs with "lr=on" param and in the 200 OK or ACK you get only "lr"
param
(with no value) ?

Hi list,
I have a routing problem with my Opensips
version: opensips 1.6.4-2-tls (i386/freebsd)

Indeed Opensips is unable to route ACK packet to final
destination
(look
attachement .txt).

The only difference with a normal call (Call OK), it's
Record-Route
formating. Customer's device send 200OK with differents fields:


Test device with the problem (call NOT OK):
Ex: problem call = 1 field for 2 routes
Extract from the customer

    200OK

Record-Route:
<sip:8.8.8.8;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>,<sip:9.9.9.9;lr;r2=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>


Test with another device (call OK)
Ex: normal call = 2 fields for 2 routes
Extract from the Customer 200OK

Record-Route:
<sip:8.8.8.8;r2=on;lr=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>
Record-Route:
<sip:9.9.9.9;r2=on;lr=on;ftag=c97942d9-13c4-50237efd-8d49d7d0-5fb68102;xyz=3a2.86da31c4>

My question is: This opensips version is able to work with 1
record-route
field containing 2

    informations ?

Thanks in advance

regards
