[asterisk-biz] User registred but can not call them

[Rehan AllahWala]

Dear All,

I am having a problem with my real time 1.2.4.

The users are registered but when you call them, it comes as congestion, or busy.

When i create the same user in sip.conf it works just fine.

I am unable to put my finger on what the problem is, but it used to work fine, and then i 
re-did the entire server, and this has started to happen.

I talked with a few people, and they suggest to use openser for proxy purpose rather 
then asterisk.

Any clues would be deeply appreciated.


Rehan
