MTP required uncheck as of the moment. codec G711uLaw and No authentication required.<br><br>Problem:<br>Outgoing call from IP Phone to PSTN gets fast busy signal. When placed a sniffer in between CCM7 and B2B gateway, i didnt see any sip invite initiated by the CCM7. CCM7 and ip phones only have traffic reachability to B2B but not Huawei.<br>The provider (B2B to pstn) was tested using altitude(as claimed by the customer) and works fine but we are testing using CCM7.<br><br>Question:<br>1> Am i right to use CCM trunk to connect to the B2B sip?<br>2> Any additional configs i need to configure? Misconfiguration?<br>3>Should i expect SIP invite to be sent by CCM when call is triggered by ip phones?<br><br>Thanks,<br>Jeff<o:p></o:p></p></div></body></html>
