upper registration + dial plan

i want to register with another sip server using brekeke sip server.
like...
suppose if i use 101 id for registration.

then 101 is for brekeke and 102 for another sip server will be registered.

is it possible

how?

what about dial plan?have there any location from whare i can learn dial plan rule easily...

Thanks

do you want to register a client as 102 in another SIP Server if the client registers 101 in the Brekeke SIP Server?

yes i want to do that...

DialPlan can do it..

which softphone are you using?
if your softphone can work with multiple registrar, set 101 with brekeke SIP server's address and 102 with another SIP Server's address.

Thank you Both for your reply...

when i m doing upper registration then the user is registered with two sip server. right?

that is i have to put the user in the user list(user Authentication in Brekeke menu) in both two sip server. right?

opu.

Yes, you are right.

Are you using Brekeke for both SIP servers?

no i am using brkeke and cordia. i want to register with cordia using brkeke....

if two brekeke is perform well for this purpose. then i think brekeke and cordia will work....(may be i m wrong)

thanks for your reply....
