Re: [Serusers] sip load balancing

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 ?
