[Asterisk-Users] Voicemail/Record sending no RTP packets (CNG) back to caller when recording messages

2005-10-20 Thread Ted Cabeen
In August and September of last year, there was some discussion of
changing the Voicemail and Record applications to send back CNG RTP
packets during recording to prevent inbound calls from dropping when
they assumed a disconnect after 30 seconds of no RTP frames.

Was there any resolution on this issue?  I'm bringing up a new SIP
provider, and am seeing the same behavior that was reported a year ago
with BroadVoice, although on my system the disconnect happens after 10
seconds.

[Asterisk-Users] Two Zap Problems with 1.0.2 that appeared at the same time: choppyness and squealing

2004-12-08 Thread Ted Cabeen
I've got an * system that is having some real problems with 1.0.2.
The biggest problem is that calls going through my T100P get choppy
for about 10 seconds every 1 or 2 minutes.  Asterisk is running on a
debian stable system with current packages.  The T100P is plugged into
a Adit Channelbank with 8 POTS lines hooked up to the Channelbank.
I've watched the vritual memory and CPU status on the * box during the
call and the system is totally idle.  Looking at the verbose logging
in *, there isn't any obvious activity on the console that corresponds
with the choppyness.  It sounds like this is the echo canceller having
problems, but regular phones plugged into the lines sound fine.  In
early November, this system was running fine on 1.0, but even
downgrading back to 1.0 now doesn't fix the problem.  Any thoughts?

The other problem is related to our legacy PBX system, which we
route through * when the * is being tested.  To do so, we run the 7
PBX lines into a FXS card on the Channelbank and configure * to bridge
the PBX lines to the POTS lines as necessary.  The problem is that
when the employee talking through * on the PBX hangs up the line, the
caller coming in through the POTS line hears a very loud squeal for a
second until * hangs up the line.  I've run the channelbank with a
loopbacked T1 replicating the same problem, and it doesn't happen, so
* is definitely involved somehow.  Is there a setting to determine how
asterisk detects hangups on FXS Zap channels?

Re: [Asterisk-Users] ADSI phone vs. IP phone

 Why wouldn't you just use your existing Ethernet infrastructure putting
 the  IP phones inline between the wall jack and the PC? There are a
 number of IP phones that have builtin switch/hub that allows the PC to
 daisy chain off the IP phone.

 To quote myself:

 True, but I don't have to retool my office and install POE switches to
 use ADSI phones, either.  No, I will not put a hub/switch at every desk
 and then use wall-warts for every phone to get around retooling the
 office.  :-)

 I'm not going to bastardize my network by placing the equivalent of a 3-port 
 switch or hub at every desk to have the phone system compete with our heavy 
 network users (CAD mostly), and I will fight tooth and nail against having 
 to put a goddamned wall-wart at every station just to power the damned IP 
 phones.  :-)

Do ADSI phones need wall-warts, or can they drive themselves from the
line power?

Re: [Asterisk-Users] max queue time; newbie question (fwd)

2004-01-13 Thread Ted Cabeen
Martin Pycko [EMAIL PROTECTED] writes:

 sure, use the 'n' option of the queue and put voicemail app as the next
 priority

Will that work?  From my read of the code, the timeout parameter is
only checked while the call is being sent to an agent's phone (inside
the try_calling function).  The timeout doesn't seem to be checked
while the user is waiting to get to the head of the queue (inside the
wait_our_turn function).  Unless the ast_waitfordigit function checks
the timeout and I missed it, this solution won't work.

Am I reading the code right?

 I am just studying Asterisk now and have a question.  Is it possible to
 force anyone who enters a queue into voice mail after they have been in
 the queue for 30 seconds?
