VoIP: Call routing


Overview


Applicable to any call between any type of ports (local or voip).


Any call routing is possible except VoIP
-
> VoIP call


Implicit Routing


Easy to configure : no called number configuration


No number processing


Routing Table


Incoming call routing :
optional

process done for each incoming call (from
VoIP network or local port)

allowing number translations (calling & called
numbers) and voice profile selection


Outgoing call routing : for numbering plan definition (overlap or in
-
bloc),
selection of the remote voip device if no gatekeeper, number translations
(calling & called)


Possibility to configure a backup route in case of outgoing call failure


Possibility to modify specific ISDN Information Elements :


Type of number, Numbering plan, Bearer capability

VoIP: Call Routing


Up to 200 routing rules can be configured


Type of rule: incoming (initial routing when receiving the call) or
outgoing (2nd step of routing)


Number to be checked


Called or calling number


Wildcards can be used


Related port (local or VoIP)


Actions: Number translations, ISDN I.E. forcing


Definition of backup routes


The rule order is important: the rule #1 is checked
first


Insertion & deletion of rules by using the rule index

VoIP: Call Routing


Routing Process for call coming from a local port


1. The incoming rules related to the local port are checked down the
rule list


If matching the rule (number & port), the number translations are
applied


The check of incoming routing rules can be processed again until the
last one. This possibility allows to make several number translations on
the calling and called number.


2. The outgoing rules are checked from the first one


If fully matching the rule, the number translations of the rule are applied
and the call is routed to the specified port (local or voip).


Backup route can be configured to define alternative rules in case
of failure.


If partially matching the rule (e.g.: incomplete number in overlap mode),
the call is not further routed and the GW waits for another digit

Routing Process for call coming from VoIP



1. The incoming rules related to voip are checked from the
first one


Upon a match (number only), the number translations are applied


The voip port (coder profile,etc) is determined


Check of routing table can be processed again until the end of the
table


2. The outgoing rules are checked from the first one


Outgoing rules with voip port are excluded (no voip
-
voip routing)


Upon a full match, the number translations are applied and the call
is routed to the specified port (local or voip).


Backup can be configured to define alternative rules in case of failure.


Upon a partial match (ex : uncomplete number in overlap mode), the
routing process is fully cancelled (done again with the next digit).

Routing on local port


Configuration of a port group


Same number for several ports


Incoming Calls are distributed with a configurable priority


Possibility of call hunting


automatic backup inside the port group


higher priority is given to «

Several numbers can be configured for each port

Registration to registrar server (user=phone).


E164 Prefix is mapped to a pots
-
group or a voip resource. To register it,
<ua
-
sip> must be added. Corresponding prefix is used as user portion of
sip uri of To/From/Contact header field


To register a username instead of a E164 prefix (no user=phone), sip
-
username must be validated. It overrides «

prefix

» value for
To/From/Contact header fields for register method. It overrides «

prefix

»
value for From/Contact header fields for Invite method.


Registrar ip address or domain name must be configured at the sip
-
gateway (reg

-
add)


401 or 407 challenge for register and/or invite method. Sip
-
authentication <username> <password> are provided to calculate
