Hi Ismo,
SIP and H.323 can run on the same Gateway,
it is all do to with how you configure your
dial-peers. A dial-peer tells the Gateway a
destination for a call based on a source.
If a call matches a destination-pattern
configured in a dial-peer, then it will use
that dial-peer to find the destination,
whether the dial-peer is configured to use
SIP or H.323 (for a dial-peer configuration,
H.323 is the default protocol used, where as
SIP has to be specified).
You can use the preference command to
configure both protocols for a destination-pattern
but prefer one over the other, and fall back
to the secondary dial-peer if the primary
destination is unavailable.
Below is an example configuration of a
couple of dial-peers:
!
dial-peer voice 1 voip
description - H323 dial peer
destination-pattern 1...
session target ipv4:10.1.1.1
!
dial-peer voice 2 voip
description SIP dial peer
destination-pattern 2...
session protocol sipv2
session target ipv4:10.1.1.2
!
