Hi,

Can someone can tell me why the warning message is showing ?

Hi Kyle,

What’s wrong on this

 

[kyle555]

The same problem as your other threads. For some reason you're trying to make compatibility work between a phone and PBX that weren't built for each other and just happen to both talk SIP.

There's nothing wrong with open vanilla basic SIP. You can do a lot with it. You just have to be ready to debug protocol at a very low level to build the solution you want. Why don't you just buy Alcatel phones for your Alcatel PBX and avoid having to debug problems to this level? Most of the time everybody recommends the simplest solution - even if it costs money, it's better than costing your time later debugging this stuff. I can't speak for everyone on these forums, but we generally don't spend our valuable time trying to make incompatible things work just for the sake of it. You could pay me for a week and I might not be able to make those Avaya phones work. Maybe your Alcatel rep's quote to replace those phones is less than a week of my time! For reasons like that, we generally don't get to such a low level of debugging specifically to address 3rd party interop.

Just buy the right tool for the job.

The other option might be to use a Session Manager as a proxy

However, Kyle555 has makes a compelling case

Take Care

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.

Maybe you should contact the vendor of your phone system (Alcatel from the looks of your previous threads) and ask them if they support the pieces and parts you are trying to integrate to their system. An Avaya SIP phone can be a basic (dumb) SIP UA and connect to proxies and registrars other than Avaya made ones, but your functionality is going to depend on that registrar they connect and register to and how well they are supported by the vendor.

Personally I would not spend the inordinate amount of time it's going to take to make an Avaya SIP phone set work properly with an Alcatel system doing any more than basic call functionality. It just wouldn't be worth it in the long run. You will spend more money in time and effort than buying the proper phones will cost you (by far) and end up with a system that has less features.
