asterisk users - Mar 2007 - Fwd: Back to back E1 - asterisk <=> toshiba pbx -Call droping

Before studying your configs, what have you tried so far?

 

Did you change this?  

 

Also, try changing your second span timing from span=2,2,0,ccs,hdb3,crc4
to span=2,0,0,ccs,hdb3,crc4.

 

Here is the documentation on voip-info for why it may be the cause of
your issues

 

http://www.voip-info.org/wiki/view/Zaptel.conf+span+syntax


span definition format: 
span=(spannum),(timing),(LBO),(framing),(coding) 

spannum= Number of the span. 

timing= How to synchronize the timing devices. 
0: to not use this span as sync source 
1: to use as primary sync source 
2: to set as secondary and so forth 

Use '1' if you want to use the circuit as your primary sync source. If
'0' is used asterisk will try to provide timing to the span (say, if you
were connecting to a legacy PBX). If Asterisk is connected directly to
the telco you will want to use '1' to accept timing from them. If
youhave multiple spans, set them as 2, 3, 4, etc. 

Problems with timing manifest themselves different ways - with static,
pops, and channels or calls regularly dropping.

	As these problems are very time sensitive and frustrating, I
suggest you 
	document each change you make and do them one at a time so you
can
	actually know what the problem was and not introduce new
problems in the
	process.
	
	
	
	Find someone who is on the phone quite a bit and will give you
an honest 
	evaluation of the call dropping situation (unless you yourself
are
	experiencing this issue too).  Some people are so quick to say,
"It is
	still happening" without starting the evaluation from a clean
slate 
	after each change.
	
	
	
	You may want to check your Asterisk log for more insight.
	/var/log/asterisk/full.  Also you can turn on debugging on one
span at a
	time and see if you can find something there
	
	
	
	Do you have a resetinterval set in zapata.conf?  If you can
isolate the
	dropped calls to the reset interval (watch the console, it will
scroll
	with each channel being reset) then set resetinterval=never.  If
there 
	is no entry for resetinterval, add it and set it to never since
it is
	defaulted to on.
	
	
	
	Also, try changing your second span timing from
span=2,2,0,ccs,hdb3,crc4
	to span=2,0,0,ccs,hdb3,crc4.  This in combination with your
first span 
	should accept timing from the Telco and then supply it to your
Toshiba,
	I would actually try this first.
	
	
	
	Another thought, It seems you have quite a lot of hardware in
that box.
	I am not sure how much is too much, but that would probably just
rear 
	it's ugly head as poor audio.
	
	Thanks,
	Steve Totaro

	Hi Team,
	
	
	
	I have integrated asterisk with Toshiba analog PBX. NOw the live
setup
	is going.
	
	
	
	Now I am facing call droping problem. It's happening ample time.
10-20 
	calls are droping every day.
	
	
	
	What could be the reason. I attached latest zapata.conf file for
your
	information.
	
	
	
	
	
	
	
	This is being a huge issue.
	
	
	
	Highly appreciate your help on this regard. 
	
	
	Thanks & Regards,
