© 2004 Cisco Systems, Inc. All rights reserved. IPTT v Summary Use the Q.931 translators available to troubleshoot ISDN gateway and PSTN issues. Q.931 can be used to diagnose issues with intercluster trunks. DBLHelper can be used to reestablish replication by republishing and reinitializing SQL replication. Your protocol analyzer should include the ability to sniff Skinny, MGCP, H.323, H.225, H.245, RTP, SQL, and LDAP protocols. Dialed Number Analyzer can be installed as a plug-in to Cisco CallManager where you can test and troubleshoot dial plan configurations before and after a dial plan is dep l oyed.
