I have 2 Issable server (Server A and B ) that connected with IAX2 trunk to eachother. when people call Server A (From PSTN or Mobile Phone), IVR plays and they can choose their destination and extentions.
My question is: How can i connect Server A to Server B that when people call Server A (From PSTN) they choose extentions on Server B ?
Server A Extentions: 1001, 1002, 1003
Server B Extentions: 2001, 2002, 2003
