CLI ERROR:

MY SIP.CONF

[981064]
host = dynamic
from=981064

allow=g729
allow=alaw
type = friend
dtmfmode=rfc2833

It is working now after putting nat to yes... Great thanks

Answer 2

A software SIP phone running on a computer that has no gateway defined can not register with Asterisk.

1) When client computer and PBX computer are in same subnet, there is no need to have a gateway, and in fact, this is preferred in many cases for security reasons. However, this breaks SIP with Asterisk.
