[asterisk-users] problems with some incoming/outgoing calls

[Lucas Alvarez]

Hi, which version of asterisk are you running? Perhaps if you post your  
extensions.conf and others related files you could get more accurate help.
If you answer a ringing phone and you can't answer the call, there you  
could have a network or sip config problem, that means that the SIP packet  
is not returning to the pbx.
Regards.

Lucas
