Hi Folks,

I have a Cisco AS5300 in a different domain as FS, It will send calls to FS with format ( prefix + phone number ) through sip with codec G723.
here is the configuration setting on FS.

Set the default sip_profile without auth ( no need register)
<param name="accept-blind-reg" value="true"/>
Set the default dial-plan with expression to handle prefix
    <condition field="destination_number" expression="^9090180012345678$">
      <action application="bridge" data="sofia/default/180012345678@sip.gateway.com"/>
    </condition>
    </extension>

what else i need to setup? AS5300 keep getting error code 27.

Thanks for any help,

StevenLee
