Subject: Re: [asterisk-users] Dropped calls when all DAHDI lines in use
Have you given any thought to moving to at least a current supported version 13?
Asterisk 11 has been EOL for some time now
I doubt you will get a resolution to a version no longer supported.
Moving to the latest version 13 should be relatively quick and painless, and if
the issue persists you might find more assistance.

Hello,

I am running Asterisk 11.17 with DAHDI 2.9.0 and an OpenVox A800P with 8x analog
POTS lines coming into my Asterisk server from the phone company. Internally, I
have about 180 SIP clients defined in sip.conf. What appears to be happening is
that if existing calls are consuming all 8 external lines and a new SIP client
attempts to make a call, an existing call gets dropped. The asterisk log simply
shows this as a normal hangup, so I am not able to easily distinguish between a
normal hangup and this type of dropped call. In testing, I am able to get a new
SIP client to report "service unavailable" when all 8 lines are consumed, yet
still drops are reported.

I have been unable to find any configuration settings pertaining to prioritizing
existing calls over new calls. What else can I look for to attempt to debug and
fix this so that existing calls are not dropped?

Thanks,

Andrew

John,

Thanks for the reply. Yes, I am planning on moving to version 13 but need to 
find a
solution in the interim. If there are any configuration options that pertain to
which actions to take with existing calls when new calls come in, I think it is 
likely
that they would be shared between both versions (and I want to make sure I have 
the
correct settings when I switch to version 13 too). Can you advise on any 
tunables
related to handling existing vs new calls?

Thanks,

Andrew

I really can't help with your existing issue(s)
I suggest you make the switch to the latest version 13, which should go fairly 
smoothly, and you may find that you no longer have an issue.
