Hi,
Does using a different codec affect the volume of the voice?

I am trying Asterisk could manage codecs negotiations. I have some
telephones that supports g723.1 and G711, while others only support

Hi all,
Another simple question: does it make sense to use the append option in
MixMonitor (,a) when the codec is gsm? Or it works only when the codec
is an uncompressed one like ulaw, alaw or slin?

I'm also confused on how this would help with external calls (which we

Hi Folks,
We're trying to roll Asterisk out to production and are having a few
complications.
Most specifically we have G711 for our inbound origination, but would
prefer G729 for outbound termination, so far so good - it appears that
dtmfmode=auto works in both cases.
The area I'm having
Use type=user for inbound and type=peer for outbound. Have different
codec settings for each of them.

Any chance that you try to play them to a channel that uses a g729
codec?
I believe that this requires a separate g729 codec instance.
I used codec_g729.so in stable realease so i set g729

Here is an example:

On the sip side you have g729,ulaw as the codec order. That call

You are correct. Bandwidth is bidirectional. All those references
mentioned in the thread may be misleading. However, the bottom line
is that it does use 64Kbps up/down plus overhead. This does not mean
that to transport a single conversation you need ~150Kbps. You simply
need to make sure

Of course - ISDN is bi-directional. I guess saying that ULAW takes 130K+
bandwidth depending on the framing type (local lan, w/1 hop, vlan, etc)
is not very clear. Thats total bandwidth. With lots of us at home and

I am not 100% sure about this, but Net2phone do not always use
