Hello,

          I am trying to do a force drop, using an external program. This program sends a BYE to the UA, via Unix Socket (ser.sock). The Bye looks like this:

:t_uac_dlg:jm

BYE

sip:30003035@192.168.10.100:5060;user=phone

.

From: <sip:30003060@192.168.10.79;user=phone>;tag=357a0541b4a6fc93

To: <sip:30003035@192.168.10.79;user=phone>;tag=8e1f14f59d2c1f9d

Cseq: 1243 BYE

Call-ID: 64c75c67f1c0c450@192.168.10.115

.

.

This works fine!.. But I don’t receive the response of a BYE in “jm” Unix socket.

After I send the Bye, I create the “jm” Unix Socket. Next I send the BYE. And then I read the “jm” socket, but don’t receive nothing.

I have this error

5(6782) ERROR: tsend_dgram: failed to send: (22) Invalid argument


My ser.cfg looks like

debug=5 # debug level (cmd line: -dddddddddd)

fork=yes

log_stderror=yes # (cmd line: -E)

check_via=no # (cmd. line: -v)

unix_sock = “/tmp/ser.sock”

unix_sock_children = 1

In my ser debug I receive this
