Hi,

I'm having a problem with a Sipura, it is sending for the G729 the
tag "G729a" witch is not correct due the RFC.

Media Attribute (a): rtpmap:18 G729a/8000

FS is returning (200OK)

Media Attribute (a): rtpmap:96 G729/8000

I think that the problem is that FS is not matching the codec, so it
returns the first dynamic payload which is 96.

I think that I've seen post with a similar issue, and the solution was
to change the tag before it hit the switch, so, what I've done is to
change the "switch_r_sdp" (I have the rest of the parameters correct
due I also use it to dynamically change the codecs order) and it's
changing the SDP, but when FS sends the 200OK it is returning to the
endpoint:

Media Attribute (a): rtpmap:96 G729/8000

Which is exactly the same problem that I have without the
transformation of the SDP.

Is it correct? Do I have another solution?

Thanks

FIx your sipura to NOT include the a in the codec its in the admin
section of the UI on the ATA.

I think you can edit the prefs in your sipura and change it to the correct string.

Yes, that was my first option, but there many endpoints that I'm not
able to configure. Basically it's a broadband solution where I have
like 1000 endpoints that are out of my provisioning.

Thanks,

Sounds like bad planning. I would send out a memo to your users and
have them fix it. I have raised a bug multiple times with Cisco g729a
is NOT valid.

so imagine how much money all those sipuras cost.
They get all the money *and* have a bug and we are free and are supposed to break the rules for them.

I am willing to support this with the note that its incorrect and will not support it by default but update to trunk and try:
<param name="NDLB-allow-bad-iananame" value="true"/>

this should fix it for you, SIGH

It appears that Tony has already added an option (amazing) BUT you
should really be setup for central provisioning with an installed base
that large... You'll eventually have issues that *NO* amount of
Tony/FreeSWITCH magic can fix.

Actually, there were a few more misinterpretations in earlier software of Cisco Gateways, which RFC implementers had to address in RFC3551, strange ...

RTP Payload Type 19 remains reserved because "some implementations" wrongly interpreted 13 decimal as 13 hexadecimal value.
Another issue is G726 bit packing. Again "some implementations" used wrong bit packing and RFC3551 tried to partially resolve this conflict introducing new payload format named AAL2-G726 ...

Don't forget the one where there was a typo in the one for G722 so now we are all required to emulate that typo by running a 16khz codec with 8khz timestamps and sdp params.
