Activating CS context configuration 354
SmartWare Software Configuration Guide 31 • CS context overview
Finally, we configure the call router. Here we create a routing table that examines the called party number of a
call and routes numbers starting with a 1 and containing at least 3 digits to the hunt group that tries to reach
company office A over VoIP and falls back to the PSTN. We route numbers starting with 2 and containing at
least 3 digits to the hunt group that tries to reach company office B over VoIP and falls back to the PSTN.
Calls with a prefix of 5 and at least 3 digits are routed to the hunt group that selects a free BRI to the PBX and
all other calls are routed to the hunt group that selects a free BRI to the PSTN:

The hunt group HUNT-COMPOFF-A tries to reach the company office A routing the call directly to the
H.323 interface IF-COMPOFF-A. When this call fails (e.g. because the data network is broken), we route the
call to the PSTN hunt group. Likewise, hunt group HUNT-COMPOFF-B works, but tries to route the call to
the H.323 interface IF-COMPOFF-B first.
node(ctx-cs)[switch]#service hunt-group HUNT-COMPOFF-A
node(rt-tab)[HUNT-CO~]#no cyclic
node(rt-tab)[HUNT-CO~]#timeout 5
node(rt-tab)[HUNT-CO~]#route call 1 dest-interface IF-COMPOFF-A
node(rt-tab)[HUNT-CO~]#route call 2 dest-service HUNT-PUBLIC-PSTN
node(rt-tab)[HUNT-CO~]#exit
node(ctx-cs)[switch]#service hunt-group HUNT-COMPOFF-B
node(rt-tab)[HUNT-CO~]#no cyclic
node(rt-tab)[HUNT-CO~]#timeout 5
node(rt-tab)[HUNT-CO~]#route call 1 dest-interface IF-COMPOFF-B
node(rt-tab)[HUNT-CO~]#route call 2 dest-service HUNT-PUBLIC-PSTN
node(rt-tab)[HUNT-CO~]#exit
node(ctx-cs)[switch]#
The hunt group HUNT-PBX routes the call either to the interface IF-PBX1 or IF-PBX2, depending on which
interface there is a free B channel. Likewise the hunt group HUNT-PUBLIC-PSTN works on the PSTN inter-
faces.
node(ctx-cs)[switch]#service hunt-group HUNT-PBX
node(rt-tab)[HUNT-PB~]#cyclic
node(rt-tab)[HUNT-PB~]#route call 1 dest-interface IF-PBX1
node(rt-tab)[HUNT-PB~]#route call 2 dest-interface IF-PBX2
node(rt-tab)[HUNT-PB~]#exit
node(ctx-cs)[switch]#service hunt-group HUNT-PUBLIC-PSTN
