asterisk uses alaw whatever I do, except force it to one specific in

Codecs : 0x11a (gsm|alaw|g726|g729)
Codec Order : (none)
can someone please explaing why?

Codec order sent wrong from Asterisk
I'm communicating a softphone (SJPhone) to a Grandstream phone GXP-2000.
The codec order on each one is the next:
SJPhone: GSM - iLBC - PCMA - PCMU
GXP2000: G729 - GSM - PCMA - PCMU
(I have a G729 license, so there's no problem with transcoding G729)
In my sip.conf, I've defined the following codec order:
disallow=all
allow=g729
allow=gsm
allow=g726
allow=alaw
allow=ulaw

asterisk 13.18.0: pjsip: unnecessary 603 decline because of wrong codec decision
Hello!
I'm facing the following scenario:
- Initial call opened to asterisk: SDP g722,alaw,ulaw
- Outgoing call to provider started with Invite / SDP alaw, g726 and
g729.
- Provider sends 183 Session progress SDP: g729, alaw
- Provider sends g729 rtp packages
But: there is no license to transcode g729.
What is asterisk doing?
Asterisk decides to stop the call at all:
- Sends cancel

Codec negotiation : expecting G726, getting G711a (alaw)
Hello list,
Grandstream GXP2010 phone calling to Snom 320, Asterisk in the middle.
Grandstream allows for 8 different codec specifications. I have defined
them as 4 x G726 & 4 x alaw.
Snom allow for 7 different codec specifications. I have defined them as
3 x G726 & 4 x G729.
The SIP peers are both defined as :

Codec Selection in Asterisk
I am wondering how Asterisk selects codecs between devices. For example,
in my sip.conf I have:
disallow=all
allow=ulaw
allow=alaw
allow=g729
Does the order matter? Does it mean it will try each codec in succession
and use the first that both endpoints support?
Thanks,
Adi

Asterisk codecs and packet size
Does anybody knows if it's posible or if there is some develoment in
course to be able to use longer transmit packet sizes (as long as I know
this is fixed in 20ms now) with the compressed voip codecs in asterisk
(g729, g726, gsm, etc).
I need to use asterisk to connect remote sip clients with 24kb bandwidth
lines and I'm using a licences g729 codec but because I can't increase

one way / irratic voice over iax and g729
Hi All,
We are experiencing a a problem when running calls over IAX with g.729.
The call flow is as follows:
Sip handset -(SIP)> Asterisk1 -(IAX)> Asterisk2 -(SIP)> Carrier
The first Asterisk system is running 1.2 and the second is running 1.0.
When using g726 from the handset all the way thru to Asterisk2(then 729
for the carrier leg) calls go thru fine, but when using g729, there

asterisk sipura and g726 codec
With sipura (I tried this with both the 3000 and 841) set to prefer
the g726-32 codec, a call from the sipura to asterisk will use g726.
Asterisk sip.conf has:
disallow=all
allow=g726
allow=gsm
allow=alaw
When the call is from asterisk to the sipura, asterisk will not use
g726. It ends up using alaw. I usually use stable but I tried this
with head too, and same thing happens.
Anybody know how

My G729 problem re-visited
Ok, I built a test system to duplicate my problem and provide myself
a platform that I can mess around with to try and break any features.
My problem is G729 pass-through from a gateway to a phone. I think
I even have transcoding working, which makes me more confused on
what's wrong with my pass-through. It must be a configuration issue.
The basics...

G726-16 passthrough...
Hello,
I'm wondering if anyone has benn able to successfully get g726-16
passthrouhg to work? I am wanting to use this codec instead of g729 as
I'm running out of DSPs using a high complexity codec on the Ciscos. I
would think it would work just as g729 does, which has been working fine
for me, but it does not. G726-32 does work great however, but it's like

Best Codec
We are evaluating starting a small VoIP consumer based platform.
What is the best codec to use with customers using primarily DSL as
internet connectivity?
I know that g729 is the king-all, but I want to know what the rest of
the professional are using out there. g729 has a cost involved, so does
the cost really offset the performance? Or is it better to go with g711
to start off?

sip ... codec conversion matrix
Hi,
I have asterisk 1.2.18.
I just took a peak at the command: > show translation
and I saw that I can only convert from/to ulaw, ulaw, gsm and slin.
No speex, no ilbc ... do I need a license or compile something extra?
The G723, 726 and 729 ... I need a license, is that it? one for all of them?
or for each?
How do I get them to work? not just pass-through ... I need conversion.
Thanks a
