UCx50 w/BCM Digital Gateway
(OP)
Folks I have a UCx50 with a BCM digital gateway. Customer is losing calls after about 2 min on the phone. These are outgoing POTS trunks. 8 are DAHDI and 8 are SIP to POTS. Seems like a supervision problem, but then I'm open to suggestions. Ideas please?
RE: UCx50 w/BCM Digital Gateway
Are calls lost on outgoing only?
RE: UCx50 w/BCM Digital Gateway
UCx analog trunk card on board
and the customer believes incoming, but they have both way trunks assigned.
'Course it never happens when I am there waiting for it.
RE: UCx50 w/BCM Digital Gateway
has telco checked the lines at the demarc?
RE: UCx50 w/BCM Digital Gateway
Phone company there today. No problems. Got to think it's a gateway programming issue; I checked everything on the UCx looking for some type supervision setting on the trunks. None that I can find.
RE: UCx50 w/BCM Digital Gateway
The gateway would be a likely cannidate due to the many configuration options

RE: UCx50 w/BCM Digital Gateway
ask your customer if they could try to make note of the time when it happens
with that you can narrow the search through call records and log files for a clue to whats going on

in the corresponding SIP trunk configuration. As far as I remember, this option is required for Grandstream gateways (some others might need it, too).
If the disconnects happen on the internal card's trunks, look at Global Settings on the PSTN Cards page - specifically at the three Busy Detect related settings. If you have Busy Detect Enabled set to Yes, make sure the Busy Detect Pattern matches the cadence of the tone the CO sends when far end disconnected the call (e.g. set it to 500,500 if the tone is on for 500 msec and off for 500 msec). Also, set the Busy Detect Count to something like 10 to avoid false detection.

I have v4.0 s/w. What am I missing please?

Also, if you can get the customer to do a "Feature 9*9" when the calls drop this will do a Log Stamp in the Support Logs that may give an indication of what's going on if you need to open a ticket with E-Metrotel.
Hope this helps and have a blessed day!

Go down to the "Disconnect Supervision" section and then read the "On a Release 4.0 System" section. This explains how to check the settings in the chan_dahdi.conf file

The busy pattern should be adjusted to match the cadence of the disconnect tone from the CO (i.e., the tone generated by CO after the far end disconnects).
With the options above, the call processing software will disconnect analog trunk calls (internal card only) when it detects 10 repetitions of 500 msec of tone followed by 500 msec of silence. The tone does not have to be any specific frequency. In fact, even speech could trigger the disconnect (especially with a low value used for the busycount).
If you don't need the busy detect feature (e.g., when disconnect supervision is implemented using polarity reversal), the feature should be disabled (to avoid unexpectedly terminated calls) using
RE: UCx50 w/BCM Digital Gateway
busydetect= yes
busycount=10
I do not have a busypattern=500,500 as a line
I have 4.0 sw
so just mark busydetect=no then? I do have supervision w/polarity reversal from the LEC
RE: UCx50 w/BCM Digital Gateway
I've had a case when the telco trunk would not give supervision at times!
