I have several IPTs on my CIX-40 that work well. I configured one of the extension to be SIP instead of IPT. I downloaded X-Lite free SIP client and now I am trying to connect to the PBX using the software.
I setup the account with the
account name : 127
password : 127
domain : the ip of the MIPU card

When I connect, it says "the phone is enabled" so I guess that the parameters are OK. If I change the domain and or password, it says "cannot enable the phone".
Trying to place a call, either to a local extension or an external extension, it says "Failed to establish the call".
Is this supposed to work with only these basic settings?
