CUPS - OCS rcc is not working


Does anyone had a similar problem to this:

When a user uses his moc for rcc in one location it works fine but at the same site, another building it does not work anymore

traces from CUPS reveal the following:

PID(10009) sip_tcp.c(5472) IPC message read event

Anyone know what failed to acquire scb stands for?




Re: CUPS - OCS rcc is not working

Hi Koen,

I don't think this is related to your problem.

I would start sniffing on OCS and CUPS along with SIP proxy traces while reproducing the issue and see what happens.

I would also compare a working and non working scenario (first in the sniffer traces then in SIP Proxy traces)

Here is how you enable the built in sniffer in CUPS

SSH to the box

utils network capture eth0 size ALL count 100000 file cups

Here is how you get the file

file get activelog platform/cli/cups.cap

You need an sftp server

Alternatively you can use RTMT to get the capture file (you can do this with the latest versions).

Hope this helps
