Trying to call a T.38 enabled endpoint B from an endpoint A that doesn't. This
results in a "488 Not Acceptable" from A.
The kamailio (4.0.3) in between with topoh enabled (with mask_callid set to 1.
Kamailio ACKs the 488 to A, but the ACK has the wrong (masked) Call-ID,
resulting in the ACK to A being ignored, A keeps sending 488 at intervals
before just dropping the call.
My understanding is the Call-ID in the ACK has to be the same as the Call-ID
from the 488. But instead of sending the unmasked Call-ID used in all other
messages between A and Kamailio, the ACK contains the masked Call-ID used in
all messagea between A and Kamailio.
I can't find a bug report relating to this. Is this a known feature or maybe
fixed in newer versions?

To understand properly, this is after the re-INVITE from B to A? I will
look in the code as I get a chance, being out of the office for few days...
Cheers,

Yes. Full trace below. Only the ACK to SIP_A for the 488 has the wrong Call-
ID.
Disabling masking fixes the problem, but I need topoh with callerid masking to
enable an Avaya IP Office to make calls to itself via its external extensions.
There is no hurry, it appears have been broken for a long time, a few weeks
extra makes no difference to me :) I'll try a test server with a more recent
version to see if the problem was fixed since 4.0.3.

It is an ACK for a negative response, therefore it is hop-by-hop
(received and discared by kamailio, then a new one is generated to the
next hop). The information of direction which was detected with Route
header ftag cannot be done in this case. I will try to figure out how
can be solved...
Cheers,
Daniel

To understand properly, this is after the
re-INVITE from B to A? I will
look in the code as I get a chance, being out of the office for few days...
Yes.
Full trace below. Only the ACK to SIP_A for the 488 has the wrong Call-
ID.
Disabling masking fixes the problem, but I need topoh with callerid masking to
enable an Avaya IP Office to make calls to itself via its external extensions.
There is no hurry, it appears have been broken for a long time, a few weeks
extra makes no difference to me :) I'll try a test server with a more recent
version to see if the problem was fixed since 4.0.3.

Am I to naive to think that these ACKs to negatives always (callid masking and
whether topoh is active or not) need to use the Call-ID from the negative (in
this case 488) response? Call-ID has only to be rewritten in forwarding the
negative response towards the endpoint that triggered it (which is done
correctly in my call trace)

Attached is a diff to topoh_mod.c that implements above (with my limited
knowledge). Locally generated ACKs don't get masked Call-IDs to downstream.
Works for my 488, will test some more to see if nothing else is broken. But
maybe somebody more in touch with kamailio source code could take a look to
see it this patch looks alright?

I was a bit optimistic, patch breaks if the called endpoint responds with a
4xx :(

One solution I thought of is to propagate the direction via topoh
'cookie' header, as it is done by the dialog module for the local
generated BYE. Tm code needs to be changed, but I haven't found the time
for it yet.
Being an hob-by-hop ack for a within dialog request, there is no info
that can be used to determine the direction. Topoh hooks are in the
core, after the new sip message is printed, with no relation to
transaction (or in this case, the reply).
Cheers,
Daniel

Works for my 488, will test some more to see if
nothing else is broken.
I was a bit optimistic, patch breaks if the called endpoint
responds with a
4xx :(

I also found a similar flaw with reINVITEs due to session timers in 4.2.4
A new random callid gets generated and sent to an endpoint, which reacts with
a 481.
109.235.34.226 contain the endpoints
109.235.32.240 is a loadbalancer
109.235.32.243 is the sipserver doing the topoh stuff

New subject: X-RTP-Statistics interpret ?
Hello,
I added code to include insertion of "X-RTP-Statistics" header into the BYE
message. I do see some numbers in it but I have no clue what they mean ? Any pointers ? Is
it defined somewhere. I searched a lot and could not find any info.
X-RTP-Statistics: 60 359 435 794 0
thank you very much
