I see. Have you looked at what the lcr module can do? You could possibly
create patterns for different gateways and thus create a "static" load
balancing with multiple GWs that can be picked up in failure route.
If not, maybe extending dispatcher could be an idea? It's generally
better to build on existing functionality in existing modules than to
introduce another one. Your module would then probably not be taken into
CVS...

I got the dispatch module working. The only thing
that
was of concern was that it does not failover to
another server on the dispatcher list if one of the
servers fail. So I need to have a dedicated backup
server {failure route} just to field these calls. I
guess this cannot be done since the dispatcher is a
stateless module {like Andrei mentioned}

Without completely
understanding what you are trying to accomplish: Why
can't use that module?

I have a same problem as explained below.
PSTN ---> VOIP GATEWAY(Cisco AS5400) -->
SER-------> Multiple media
gateways.
Planning to depoy media servers which can able to
running IVR
fuctionality and would like to use SER in front
of
lot of media
gateways.
Each media gateway, might be running lot of user
agents which are able
to serve IVR fuctionality. all these user agents
are going to register
with SER with <media server hostname_channel
number> format as user
name. Eg. mediaserver1_ch1(a)mydomain.com
Otherside, SER will receive call from PSTN through
VOIP Gateway with
multiple DIDs and these calls need to route calls
to media gateways (
typical hosted call center environment )
I have tried with lot of possibities using ser.cfg
file and did n't
find way to route calls to media gateways.
Just I am thinking, it would be possible to write
another module or
part of userloc module, which gives a routing
fuctionality like cyclic
or rotary senarios which helps load balancing and
easy maintenance of
media servers.
Possible solution
------------------------------
Lets assume, if we have resource file called
resource.cfg which has
all did and resource mapping. All resource names
are substring of
usernames of useragents in media servers.
resource.cfg
##########################################
resource:resource1 =
mediaserver1,mediaserver2,mediaserver3,mediaserver4,mediaserver5
did:8005551212 = cyclic:resource1
did:8005551213 = rotary:resource1
##########################################
every invite message need to call fuction like lookup_route()
instead of lookup() in ser.cfg
this fuction instenally calls routing module,
searches for did in
resource file and get corresponding resource
type(
rotary or cylic),
resource name.
search each resource member in useloc using
function get_urecord and
it if avaialbe and route calls to that particar
user.
Summary:
1. ser receives call from PSTN
2. Finds resource name for DID
3. Find resource string depend of type of routing
from resorce list.
4. Serach usrloc database with resource string
as
sub string of
usernames in userloc database.
5. Forward call to that particular media gateway.
Welcome for any comments and thoughts ?
Thanks,
