This is the first time I've configured an ISDN PRI (USA) on a 4000 series router with the new NIM-2MFT-T1/E1 module and PVDM4. I have a PVDM4 on the motherboard as well as one on the T1 module.
My problem is I have NO audio coming IN from the outside call (ISDN PRI/T1). Audio going OUT on the ISDN PRI is fine - if I speak into my desk phone at the office, I can hear my voice on my mobile phone when I call it).
Audio internally between phones is fine and between phones at other locations is fine (if I call internally from this location to another location).
If anyone can help me solve this, I'd greatly appreciate it! I'm onsite for this office move right now and it's not working which is a huge problem. I see no errors when I do a debug isdn q931. The T1 controller is up with no errors and the ISDN status shows good (MULTIPLE_FRAME_ESTABLISHED)

Also, when I look at the web page for the phone that made the call (during a live call), it's not showing any received packets. For some reason, it's just not recieving anything from the outside call. This is the past that has me stumped. I'm not sure why it's not getting any audio from the outside call on the ISDN PRI / T1 module...
