GXP-2000 MultiPurpose Keys
Is it possible to program the multi-purpose keys on a GXP-2000
remotely via a TFTP configuration file? If so, what are the
parameters to put in the configuration file?
Thanks,

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
And my peers shows this order correctly:

How can I force Asterisk t not override my codec order?
I've noticed the following situation:
In two softphones, I've configured the next codec order for each one
softphone 1: 1 - PCMA
2 - GSM
softphone 2: 1 - GSM
2 - PCMA
and in Asterisk, the order is:
disallow=all
allow=gsm
allow=alaw
If I call from softphone 1 to softphone 2, I presume that Asterisk
should do transcoding (canreinvite is set to no):
softphone 1 <- PCMA -> Asterisk <- G...

About lossless and point stereo
...and and hope I can get some guidance on.
I understand the decoding/decoupling part as it is the same as the one
described in the stereo docs:
From mapping0.c:
/* channel coupling */
for(i=info->coupling_steps-1;i>=0;i--){
float *pcmM=vb->pcm[info->coupling_mag[i]];
float *pcmA=vb->pcm[info->coupling_ang[i]];
