[Freeswitch-users] Doubts over G729 passthru for 50ms ptimes

[Ben]

I tried setting the {passthru_ptime_mismatch=true} variable in the dialplan,
but no joy unfortunately.  I'm also fairly sure that the codecs are matched
on both call legs, so shouldn't be having that sort of issue.

 

I'm going to gather up some evidence and console logs/traces etc so that I
can put something together for a bug report on Jira.  Is there anything else
that someone can suggest I try before it goes on Jira?  Is anyone able to
re-produce the same problem?  Admittedly, I'm not on the latest GIT, but I'm
on a recent (last couple of months) stable release. 

 

Thanks in advance for any assistance!

 

Regards,

 

Ben

Hi Brian, yes I've set G729 at 50i on both the external and internal sofia
profiles statically, and confirmed the allowed codecs by running "sofia
status profile profilename".  

 

I can also confirm in the FS console that codec comparisons for both the
a-leg, and b-leg match instantly to G729 at 50i.

 

Clive, thanks for the pointer, although in my case I don't think there's a
mis-match as each side of the call supports sending/receiving G729 50ms
ptimes, and is negotiated correctly in the SDP.  However I'm still willing
to give it a try as I need to try everything!  I'll let you know what
happens.

 

Cheers,

 

Ben

Hi

 

I have had limited success with :

 <action application="bridge"
data="{passthru_ptime_mismatch=true}sofia/gateway/icall/$1 at 1.2.3.4"/>

 

Sometimes the sound was garbled, sometimes worked fine, not sure why it was
sometimes garbled, so I dont use it anymore, as complaints are not what I
want :)

 

Hope this helps.

regards

Clive

Hi All, 

I'm wondering if anyone out there is using G729 with 50ms ptime through
Freeswitch, without proxy media?

I am unable to get this to work, even in a very basic lab with just two
clients and an up to date FS server on the same LAN. I can get G729 with
20ms working, but 50ms causes Freeswitch to hang the call.

It might be that mod_g729 and mod_com_g729 simply don't support it, so if
anyone in the know can tell me that would be great!

Further info can be supplied, I believe I have tried pretty much all
options....

Cheers,

Ben
