Ran into an interesting issue while integrating with a legacy TDM Dialer.
Dialer connects to an IP500v2 R9.0.5 via PRI using QSIG A and then places calls out to the PSTN via SIP trunking.
If the dialer experiences 60 seconds of ringing, it looks as the call being made on a bad trunk and flags it as an error instead of Ring No Answer. The carrier can not make an adjustment to disconnect calls like this, and I'm wondering - has anyone ever come up with a way to terminate a call after 55 seconds of ringing? Seems like a GRIP may be necessary to modify the dial similar to how the Maximum Call Length feature works under Dial.
