asterisk users - May 2010 - SIP REGISTER header not containing Allow-Events or Allow

The SIP trunking service that I am trying to set up keeps saying that my
registration from Asterisk is invalid.

Asterisk registration:
REGISTER sip:{registration_ip} SIP/2.0
Via: SIP/2.0/UDP {asterisk_ip}:5060;branch=z9hG4bK5c2eb10c;rport
Max-Forwards: 70

They are saying that the Asterisk registration doesn't have an
"Allow-Events" and an "Allow" in the header.  Would this
cause any
problems and can this be set in Asterisk to send those in the header?

Thanks.
