[Serusers] How can we connect calls of two independent unknown SIP domains.

Hi all, Here is a scenario, i m working on, If anyone can comment on it. Scenario: I have two SIP domains, abc.com and xvz.com sip.abc.com is running ser and has registered users with xxxx(a)abc.com similarly sip.xyz.com is serving users xxxx(a)xyz.com sip.abc.com and sip.xyz.com can be resolved through standard dns servers as SRV hosts for their respective domains. There is no explicitly defined routing procedure on ser.conf for other domain, in both SIP servers machines. Is it possible for xxxx(a)abc.com to register with sip.abc.com and place a call to user xxxx(a)xyz.com. While trying, i m getting no packet on sip.abc.com not sip.xyz.com for the subject call. Any comment? JF --------------------------------- Do you Yahoo!? The New Yahoo! Shopping - with improved product search
