Hi Jean,
I have an Asterisk 1.12.18 with about 30 pc each with a Doro SIP phone
on an unknown LAN.
I think google is useless in cases like this.
Many of the system we are working on are in production and we cannot
make tests with them so the only hope is to gather infos from people
experiencing the same problems and trying to understand something from
the code, maybe asking the developers for info...that's why I'd like to
understand what kind of frames Asterisk is waiting for in order to find
what is the cause of this problem (maybe this is not the right
mailing-list ?)
The strangest thing is problems like this are still happening and remain
unsolved.but a PBX dropping calls (or not dropping at all, as
sometime happens) is like a car without seats.yes, you can drive,
but it is not a comfortable experience!

I have googled a lot to find solution to the same exact problem
described in your message but no real solution yet.
here is my config
1 physical network
25 pc windows
25 phones IP330 IP550 SIP 2.1.2 no vlan CDP disabled some with dhcp
some with fixed ip to see if there is a diff
3 switchs connected to each others
1 cisco switch 35xx for pcs
2 linksys 24P P OE for phones
1 patton PRI gateway to isdn
1 asterisk server 1.12.18 talking sip to Patton , for each phone, type
friend can re-invite no, nat no
symptoms:
call drop randomly , can be after 10 s or 2000 seconds ! same log
didn't get frame etc
fews drops per phones per day but very irritating for the customer :-(
tried to power phones with adapters to avoid power pbs from the switch
, same result
if someone met this problem before get an idea to fix it , I wd
appreciate !
thanks

Hi,
sometimes Asterisk drops calls and shows Didn't get a frame from
channel in its log file. Unfortunately Google gives no answers
even if
a lot of people ask for help.
A fast look into the code shows Asterisk entering a loop where
voice is
been transferred and every loop Asterisk waits for a frame,
exiting the
loop if no frame has arrived. It seems to be a problem not
depending on
the kind of channel...happens with ISDN and PRI lines.
What is stopping the frames, making Asterisk exiting that loop and
dropping the calls?
Thank you.
Giorgio.
