has anyone tried this yet?
We just cut over to sipx (4.2.0) and are not going to make any changes
till we figure out what we broke already, but once done, I think $40 for
4 concurrent G.729 paths couldn't hurt. (if it works, and doesn't get
overridden by sip restore).
I suppose we should manually back any of that up, including any custom
patches we made.

If you add G729 to the codec list for FreeSWITCH (assuming you care
about G729 support for bridged calls and you do not want to hear
silence for MOH and assuming that G729 support implies FreeSWITCH will
stream MOH using G729), you may want to make sure it is also added to
the allowable codec set for sipxbridge. See the advanced screen of
sipxbridge configuration.

Yeah, the codec appeared in the web browser menu, but I couldn’t get it to

I believe the newer models support iLBC, but I couldn't get it working.

We are using Polycom phones and I don’t think they support speex or ILBC (at

FYI I just confirmed using the X-Lite Client that FreeSWITCH supports both
the narrowband and wideband speex codecs. From what I understand it's lower
bandwidth than G.729:

I couldn't get iLBC to work with FreeSWITCH/Polycom/xLite so I gave up on
it.

Does your ITSP support speex or iLBC? If so, consider the following:
in /etc/sipxpbx/freeswitch/conf/sip_profiles/sipX_profile.xml:
<param name="codec-prefs" value="G722,p...@20i,p...@20i,speex,L16"/>
speex is supported by FreeSWITCH and it's a very robust low bandwidth codec
albeit at some CPU cost. It's also already preconfigured in sipX's
implementation on FreeSWITCH. Adding iLBC should be as simple as changing
that line and possibly a few others in other FreeSWITCH config files by
adding i...@30i to that list.
Perhaps you could do G.729 for phone-to-phone calls and then let FreeSWITCH
do speex? Am I missing a reason why this would not be possible?

I really ONLY care about AA/Voicemail/Conferencing (since everything else
seems to work).
I am assuming the only time I will need it is in freeswitch, caller using
G.729, hits AA/vmail or conference. I get 4 licenses, I am assuming 5th
concurrent caller (using G.729) will probably not hear anything. in the
case of conferencing, oh well. in the case of AA or vmail, maybe he will
call back.
maybe 10 licenses ($100) isn't all that much to spend if it works.
I thought I did turn off everything in voip.ms except G729 and the caller
can't reach AA or Vmail if the user doesn't answer.
(you on 4.2.0 yet?)

I may be misunderstanding your configuration, but it seems like if you don't
care about AA/Voicemail/Conferencing then the freeswitch license isn't going
to help (or hurt) you at all.
If your remote callers would be better off with a different codec you could
try to limit the codecs their endpoint s/w or h/w will allow (ie: don't
advertise g711 at all, just uLaw and g729). If your remote users are on POTS
then your issue is between you and your ITSP and you could limit your ITSP
configuration to the codecs you like (for instance with voip.ms I can pick
which codecs it will accept, I turned off g711 and gsm so now it always
negotiates uLaw which is pretty good; I wish they had g722 as an option too
though).
