"No resource" with VoFR

[pferraz]

Hello.

I had a VoFR topology working OK for about two years.

I've now changed the equipment from a 2600 to an 1760 but kept the same configuration (both hardware modules and running-config).

the only difference (beyond the 2600->1760) is that the IOS in the router is now 12.2(4)YB.

The problem is that now I can't make any calls outbound from that site. The output from the "show dialplan number 5160" shows "disconnect cause : 2F" (no resource).

I haven't implemented any kind of CAC so I would like some help to figure out what can be happening! Thanks!

hello.

"no resource" on voice calls should yield a problem with the dsp's. does the ios recognise the dsps? (sh voice dsp)

what was the ios-version you used on the 2600?

The DSP's are working fine since I have calls coming inbound.

I've done some more troubleshooting and found out that the call reaches the remote router, and it's the remote route that sends the "no resource" message backwards to the 1760.

Any comments on this?

(the previous IOS was 12.0.something)

thanks
