Dear
mates,
I need your support in the below mentioned problem that I experienced and
still not resolved in ISUP connectivity with ZONG. Please advice if you have
any
remedy or clue.
I have successfully established SS7 links with the Telco and they are
working fine. I have tested an outgoing call and an incoming call as well.
The problem
arises when I tried to define extension in it.
At first I just add one dialing code as 6789 and successfully received a
call over it on default extension. When I add another dialing code and
define
extension for it gave an error as
