SIP working on OXO

[henk1964]

It did take a long time but it works.
Problem is with all the RFC's on SIP and the way Alcatel wants to do SIP
There was some discussion with opening trouble tickets and emails to Alcatel help desk.

How it normaly on IP Phones, Phone is registered as USER with the accountname and password
How it works with Alcatel, OXO is trying to register as TRUNK
Reason for this is simple, Alcatel wants the SIP provider to work as a TRUNK provider with ALL features you have on normal trunk

So the SIP provider should support DDI, CLI CLIR and all forms of number presentation.
If it does not work on your provider please find a provider that does support TRUNK registration and not only user reg...

Could not talk the Alcatel guys to support USER reg because thay feel this is not the correct way to do trunking.
Hope this helps some of you..
