[cisco-voip] Cube and upgrade from 12.4 to 15.1.2

[Mirko Maffioli]

I have a 2811 with cube license and ios 12.4 use to test voip provider
and configuration.
I'm testing a sip-ua config and with 12.4 ios everything works nice
but after i've upgraded to 15.1 when i try an inbound call i get a
"SIP/2.0 403 Forbidden".

Here is the config:

sip-ua
 credentials username USER password PASS realm sip.provider.it
 authentication username USER password PASS
 registrar dns:sip.provider.it expires 3600
 sip-server dns:sip.provider.it

dial-peer voice 25 voip
 description **Incoming Call from SIP UA**
 session protocol sipv2
 session target dns:sip.provider.it
 incoming called-number 0123456789
 voice-class codec 1
 dtmf-relay rtp-nte

dial-peer voice 35 voip
 description **Outgoing Call from SIP UA**
 translation-profile outgoing OUT-SIPUA
 destination-pattern 0T
 session protocol sipv2
 session target dns:sip.provider.it
 voice-class codec 1
 dtmf-relay rtp-nte

with "sh sip-ua register status" i see that account is registered with
provider and outbound calls works fine.

There is some related command that i miss?
