Hi, I've set up a small architecture in which an ASterisk proxy is connected to a SER proxy in two different domains. I have sip phones connected to both of them. when an asterisk subscriber "travels" to SER domain it tries to register to SER. I've configured SER to accept foreign subscribers and to REGISTER them to their initial domain by the command "t_replicate". Till now everything works good, the UA is registered and Asterisk is aware of its new location, it displays in peers list the UA and its new IP address and port. The problem is when i'm trying to call the foreign UA from an Asterisk subscriber, it doesn't work. i have a TRYING response but no call establishement. how can i overcome this problem please? -- BASRAOUI Karim www.basraouik.afrikart.net
