[asterisk-users] DAHDI Error and poor audio quality

Hello Team

I have installed the new DL580 and used the new TE420B to add capacity on
our ivr. Before I put new E1?s I decided to first move the old e1 from the
old system to this new one but it has errors which not only affect the
audio quality, but also cause the asterisk to refuse any call after
sometime even though the channels seems up and active {seems d-channel
fails}..

When processing calls, too much cripping and poor quality sound

Am I right in reading that you're using a HP DL580?I had very similar
problems using a DL145, earlier on, and a number of users suggested that
this might be due to custom PCI bridge chipsets on HP motherboards.
The theory is that the PCI chipsets are designed with specialist timing to
shave nanoseconds off interrupt times, so that you get better hard disk
throughput.

However, it does tend to murder E1 timing, and breaks the entire system.
I resolved the problem by using a non-branded server with a more standard
Tyan motherboard, all timing problems went away, and the system worked
perfectly.
I know it doesn't really sound very helpful to blame the entire server
manufacturer, but some others might agree, brand spanking new and shiny
might not be the best thing for Asterisk, especially these cards.

Yes it is DL580 from HP. I wanted something big for the type of load to be
used but now im very convinced that it wasn't a best shot! The major problem
I have been facing with both dell and HP, is the kernel panic!! This one
however doesn't give the panic but HDLC and D-channels disconnection does
not want to dis appear. Digium has advised me to downgrade to dahdi 2.1.0.4
libpri 1.4.10.1 and monitor the situation. Busy doing that

Shall update

[asterisk-users] AddQueueMember with Agents.conf

Hello Team

As you are all aware, digium has removed agentcallbacklogin as from 1.6.
Is anyone knows any work around to have say 20seats (SIP Clients), 100
agents call center for which user will have to login to the queue
dynamically from any extension and yet populate queue information with
own's information instead of SIP or Local channels for reporting purpose

I have tried both
AddQueueMember(<QueueName>,Local/<Extension>@context)
and
AddQueueMember(<queueName>,agent/<agentcode>,,,,SIP/<extension>)
in
vain

Please advice

Thanks
Sam
