[asterisk-users] Realtime SIP, multiple AX servers question

Tue Jan 4 09:40:56 CST 2011

Thanks Olle.  Do you suppose I am the first Asterisk user to discover this behavior? I would find that hard to believe that I'm the first person to notice...

Your idea for how to deal with sounds reasonable..

Thank you,

Bryan

Oh, that's an interesting observation. Depending on how you see it, it's a bug or a feature request.

Code-wise what you could do is that Asterisk could retrieve the information from realtime. If the sysname is not the same as the systems, it let the information be. If it's the same sysname, then erase the information.
