asterisk users - Mar 2010 - Call Drops while doing assisted transfer from remote location

Hi all,

We have our system hosted publicly and 4 phones are connected remotely at
employee's home, and when they try to do a assisted transfer to one of the
employee at the main office, the call is lost. For ex: person A calls person
B, person B calls person C for assisted transfer, and as soon as person B
hits transfer button again to transfer person A to C, the call is lost.

But in the second senario, if the same call comes to the main office and if
they try to do an assisted transfer it works properly, but only from remote
office phones connected at their homes is not working as calls are lost. Can
anyone input some ideas on why it could happen, as even in the logs it
does'nt give much information...

We are using Yealink T28 phones. Asterisk version: 1.4.21.2, dahdi: 2.2.0.2

Thank you so much for your help.

Regards
Sandesh

This sounds like a few bugs which were opened (and recently closed) related to 
call transfers. I'm not sure when those bugs were introduced, but upgrading
to a
newer version of Asterisk may resolve those issues.

I suggest you testing 1.4.21.1 on your development platform, replicate your 
issues, then upgrade to 1.4.30 (again, on your development platform) and see if 
you can replicate the issues.

If you can, then please look at https://issues.asterisk.org to see if you can 
find an existing open issue. If not, then please file a new issue along with the
console output, relevant configurations, and whatever other information would be
necessary in order to understand the problem and to reproduce the issue.

Thanks!
Leif.

Hello
I have a 4 span PRI board with Zaptel, and Im using it for a long time.
In the last days I noticed that the result of "zap show status" show a
ZTDUMMY.... but I never installed it:


o*CLI> zap show status
Description                              Alarms     IRQ        
bpviol     CRC4
T4XXP (PCI) Card 0 Span 1                OK         0          0          0
T4XXP (PCI) Card 0 Span 2                OK         0          0          0
T4XXP (PCI) Card 0 Span 3                UNCONFIGUR 0          0          0
T4XXP (PCI) Card 0 Span 4                UNCONFIGUR 0          0          0
ZTDUMMY/1 1                              UNCONFIGUR 0          0          0


What is that doing ?
Also, some people say they cant send me calls through the ZAP trunk... 
could be because of this ZTDUMMY?

Thanks
Regards
Joao Pereira

You can comment ztdummy out in /etc/sysconfig/zaptel. As for affecting icmo

Ztdummy enabled should not affect incoming calls.
