Call from FSX port on MC3810 to fxs port on a VG200

....wont work.
It works fine from MC3810 to another MC3810.
It also works when I originate call from VG200 directed to MC810.
But whenever I originate the call from the MC3810 directed to the VG200 I get no ring or anything. The RX is just white-noise.

I upgraded IOS from 12.2 to a 12.3(35).
No work. The only difference now is that I get a "beeb-beeb-beeb-beeb" (not a fast busy, but high-pitch tone beeps).

Ideas?

VG200 code:
!
dial-peer voice 10002 pots
destination-pattern 10002
port 1/0/0
!
dial-peer voice 20001 voip
destination-pattern 20001
session target ipv4:10.1.1.4
codec g711alaw
ip qos dscp af31 media
!
voice-port 1/0/0
codec g711alaw
!
!

MC3810 code:

I'm assuming it's connected FXS to FXO?

No, It's VOIP peering (see code).
One POTS phone in an FSX port on the MC3810
Another POTS phone in an FSX port on the VG200
IP-WAN (lab...pings fine) connecting the two together.
I peer off the loopbacks

Sorry I saw the title of the thread and thought you had them connected FXS to FXS and didn't try to debug the code

SOunds like a failure to negotiate some attribute of the call, try debug h245 events and debug 225 events and see what it give you

Thanks for the fast reply. I'll try that.
...this has got a buggy feel to it.

Cheers!

Doh!
It's fixed.
I had the pots dial-peers setup in my config pointing to the wrong ports.
I made the mistake of assuming cisco numbered their port# on these things from left to right.
Nope.....it is right to left....the ports I referenced were FXO ports with nothing plugged up.

Now why on earth it was working for outbound calls?
I guess my pots voice peers are only applicable for incoming calls, thus the reason my outgoing calls did not reference them?

Three hours wasted away!

Yeah the dial peers are only needed for the called number, even if that number is on the same voice router or a different one. I guess similar to an IP route, we don't care about where it came from only here it's going.
