You asked about issues. Here's what I'm facing. I was running CUCM 7.xx . Upgraded to 10.5 yesterday. the usual expected tweaking but no big surprises until I came across my vg224's. Instead of reading the ports as configured when they were registered to the new CM, all the ports were zeroed. Not the end of the world except when I rebuilt them and try to use them, I get a fast busy after dialing any outbound calls and calling in it answers after on ring and sounds like I've called a fax. I updated to newest IOS and have rechecked configs many times. MGCP gateway by the way. Maybe I've missed something but if anyone has any helpful suggestions I'm all ears.
Update: Nevermind. just a bad set of circumstances coming together to look like a very weird bug. basically configured a port off by one from where I needed it
So you got it to work using CUCM 10.5 and a vg224 with 15.1.4(M7)?
I am in the same boat and I have upgraded my ios to the same version but ia m still experiencing the same issue. Any suggestions? and what do you mean by "configured a port off by one from where I needed it" if i may ask.
Thanks in advance.
Edit: So for me the issue had to do with dtmf tones. There was a problem with the dtmf tones that the call manager was sending and the vg was sending back. We were able to correct this using MTP resources but I felt the better way was to handle this at the gateway level. So we added these commands to the vg and the issue was resolved:
