passing calling party number when transferring a call to PSTN
CM5.2 using ISDN PRI with trunk to trunk transfer enabled. We need to send the calling party number when we transfer a call out to the PSTN. How does one configure this on the CM?

If you wish to maintain the calling party number for the calls which are being transferred to third party pbx.
On both the trunks Enable the Send Connected number to "y" on the trunk group form.
But for this solution to work properly both trunks should be QSIG enabled -
When you say qsig enabled do you mean the field on page 4 of the trunk group form
QSIG Value-Added? nComment
