Dear List,
Assume that there are two different service providers and one SER in middle of them. A client needs to use/connect SER but also he/she has accounts in both providers and both supplied him/her DDIs (landline phone). Now again assume that client registers both of phones into SER. But still he/she wants to receive calls from both providers, is it possible to receive calls from different providers to that client and/or how to i setup ?
In current SER.CFG below, i only setup one prefix which is "0", but i can change it to any and/or add many prefixes, ex: 0049 (germany), 001 (usa), 0044 (uk), 0090 (turkey) to Provider 1 and 0033 (france), 0038 (italy) to Provider 2 and so on.
debug=3 fork=yes log_stderror=no
listen=212.XXX.104.XXX # This is SER's Public IP port=5060 children=4
alias=212.XXX.104.XXX # This is SER's Public IP
