[asterisk-users] AGI - Choppy Sound

Wed May 7 14:40:11 CDT 2008

Hi Marcelo,

Sorry, just realized I responded to you directly rather than the list. So
for the record, here's the list response.

Hi Marcelo,

What format are the recordings in? Have you tried converting them to the
same format?

Thanks

Hi Robert,

Thanks for replying and I'm glad you have an application running nicely
through phpAGI ...

Now answering your questions ...

what's the load on the box during the times it's choppy? 

I was testing at night ... I mean NO simultaneous calls going through the
server ... It is good machine (Dell Xeon 2.8GHZ, 1GB RAM ... cpu load < 10%)
... I also notice the problem as other calls were up too ... sometimes the
quality is bad ... sometimes good 

Are calls in general choppy during that same point or just calls going
through AGI?

I never had this problem with my normal menu ... and when I call and I have
the problem I tried to hangup and call the other number for the other menu
... and  ... no problems ...

It's hard to verify ... because I call ... it's choppy ... hangup and call
again ... sometimes it's choppy sometimes not ... 

You mention the attendant voice becomes choppy?

Yes, when I call and the call is not good, and during the same call I try to
talk to one atendant, I almost cannot hear her/his, but the sound for
him/her is good ...

That's why I don't know if it is a problem with the recordings I did,
because the agent's voice is also bad

Is the attendant totally outside of your AGI scripts?

I'm sorry, what did you mean ? Usually what I do is ... Answer the incoming
call - send to AGI - it does the logic and play some sounds - and I do and
exec_goto to an context,extension,priority that has a queue setup - and from
there on they answer the calls 

What codecs are your clients using? 

The incoming calls - IAX/ilbc

Connection to agents - SIP/ulaw

it's the same as the other menu ...

Thanks,

Hi,

I take it you've looked at all the basics, what's the load on the box during
the times it's choppy? Are calls in general choppy during that same point or
just calls going through AGI? You mention the attendant voice becomes
choppy? Is the attendant totally outside of your AGI scripts? What codecs
are your clients using?

I'm working on a pretty intensive phpAGI based application and even with a
decent number of calls haven't had any substantial problems, more so just
with load but even with substantial activity on a fairly robust box it has
been fine.

Thanks

Hi folks,

I'm experiencing some problems with sound through phpAGI ...

What I'm trying to do is a menu, doing some database lookups and so ...

But sometimes the sound become too choppy ... just sometimes .. like 1 of 5
calls ... but is a big percentage ...

And I have my current menu on the dialplan that I have no problems with it
...

I'm using .gsm for both but different recordings ...

Does anybody has had problems like that ? Is it AGI performance problem ...
even the atendant voice becomes choppy ... So strange ...

Does anybody have a recommendation ?

Thanks,
