Meet me conference with DISA service

[vad]

Usually timer 85 for transit connection - call to DISA, after user make OUTGOING call (via substitution or Speed Dialling).
With timer 85 you can make duration limitation for transit call with DISA service.
If you have case with timer 85 - you will have tone (10 sec before timer expired) and if you dial any DTMF digits - timer will be restarted.

Hi sir,

so do you think i need to increase or decrease timer 85 so that i would not get disconnect after 1 hour+ next time?
could you help me see if there's something incorrect in my setting?
thank you very much

best regards,
Johnson

At first - change timer 85 f.e. to 1200 (2 min) and check - something changed or not.
If you will have now limitation 2 min - your problem timer 85. In this case - try value 0 (usually 0 = inactive timer).

i have try it to 1200, and do the disa + meet me,
but nothing changes, the conference call still on even after 10minutes, and i'll disconnect manually.
ok. i've change timer 85 to 0 at the moment.

many thanks.

Show us all the trunk group parameters used for disa and also the output of the tabtemp command.
In addition, can you detail how are you making the test, You must discard the possibility that the disconnection comes from the calling site.

Hi,

sorry for the late reply,

scenario #1:
we have normal conference bridge using DISA combined with meet-me conference, some participants from external caller (mobile phone and PSTN) and one internal OXE extension.
after about one hour or so, all external callers suddenly disconnected.

scenario #2:
to eliminate the possibility that the disconnection comes from the calling /external site.
i try using the same ISDN trunk to call out to the conference bridge no.
from my DID 29888521 (which is myself, calling from internal extension) calling to conference bridge no using 9 (trunk group seizure) + 29888585 (conference bridge DID no) and also try some internal OXE extension as participants.

after about one hour or so, the call from external (which is myself) is disconnected, while other participants which are internal OXE extension still can continue with the conference.

Please find the trunk group parameter attached along with tabtemp syntax command.

many thanks

best regards,
Johnson
