Hi Guys,
I have a modem which is connected to a VG224. We are trying to send Fax through that modem which is connected to another modem. It looks like modem connects the first attempt but the issue is it tries to reconnect gain and again. Please have a look at the debug in below and let me know if there's something that I can do to resolve the issue. The debug is out of the main gateway connected to the PSTN.

Note the progress with PI of 8 instead of an alerting. The other side of this PRI isn't connecting the call; it is throwing an inband error before ringdown.
Are you able to make other calls out this PRI that work? If so, get 'debug isdn q931' for a good call and compare the information in the setup to see what the deviation is.
Also, what VoIP protocols are you using on the VG224 and PSTN gateway? What fax/modem switchover method are you intending to use?
And 'sh controllers t1' on the PSTN gateway doesn't report any slips, right?
