Re: [asterisk-users] WARNING[21314]: chan_zap.c:8396 pri_dchannel: Ring requested on channel 0/1 already in use on span 1. Hanging up owner.

2006-09-13 Thread Giorgio Incantalupo

Hi Steve,

I will try to make how you suggest...to use G instead of g but the 
problem remains inside Asterisk. If there is a dynamic channel 
allocation made by Asterisk, that message is non-sense.if telco 
sends a call on channel X and Asterisk has a free channel Y, Asterisk 
should use channel Y. Stop.  Why showing that message? I do not know. If 
these message cannot be avoidedwell..I'll keep it, even if it is a 
bit strange to have a warning inside a system in general.


Thank you


Giorgio Incantalupo

Can I assume then that 'resetinterval=never' did not make this 
problem go away?



To expand on my interest this...

We have a number of nearly identical installations of Asterisk. Same
H/W, same Zaptel, and same Asterisk build etc etc - All of the PRI
hardware is the same (Sangoma A101U), and a huge percentage of E1
lines in the UK are terminated by British Telecom.

Even though there is this amount of comonality between them, we have
exactly one customer who gets the already in use message seen above
on a regular basis, and a second customer who had the error only once.
The error tends to be fatal for inbound calls as it leaves the
channel locked permanently and the telco continues to try to use it :(

In almost every case there is an obvious SIP conversation on the box
that has not cleared down fully, and which seems to be holding the Zap
channel open in error. In the first company, they use a lot of WiFi
phones, and in the 2nd company they used to use WiFi phones (different
model), but don't anymore... I am assuming there is some kind of race
condition going on, perhaps caused by slow or unreliable SIP phone
responses to call closedown events.

I looked at the zaptel code where this message is generated, in the
hope that I could request a flush of the channel that incorrectly
shows this channel open (if the telco is trying to put a call through,
then the line is definitely meant to be clear!) but it was way beyond
my ability to understand.

I thought about Glare (someone else suggested that in another
messsage), but the telco uses lowest-free channel, and we use Zap/1G,
so use the highest free channel.

Any thoughts or input are very welcome.

Thanks
Steve

I have sometimes similar things happening, with a call coming in via SIP
sometimes taking over one or more zap channels (wtf?). This is with a
