Expressway transform to simplify dial string for CMR requesting traversal license

Unanswered Question

Having implemented CMR integration via Expressway, we're now trying to configure a transform on the Expressway-C as suggested in the 'Webex Meeting Center Video Conferencing Enterprise Deployment Guide (WB31) to 'Simplify the Dial String'.


The example given says 'For example, for a prefix of 7 use a regex pattern string of 7(\d{9})'.  This alone does not seem to work as the dial string coming from CUCM is 7(\d{9})@xxx.xxx.xxx.xxx:5060, so I have configured a dial string 7(\d{9})@.* and this seems to have done the trick as I am no longer seeing 'Event="Search Completed" Reason="Not found"' in the event log.


However I am instead seeing the following;


tvcs: Event="Search Completed" Reason="Service Unavailable" Service="SIP" Src-alias-type="SIP" Src-alias="[email protected]" Dst-alias-type="SIP" Dst-alias="sip:[email protected]:5060" Call-serial-number="1339e388-dede-4a81-a6b0-9f9f75164efd" Tag="c49c65ec-b179-446c-849e-a45d47f398a5" Detail="found:false, searchtype:INVITE, Info:No License Available" Level="1" UTCTime="2017-05-19 13:38:10,741"
licensemanager: Level="INFO" Detail="License not granted" call_id="a5d58fb1-b2a0-41a6-823b-ded7df5f2496" lic_type="traversal" tokens=2 UTCTime="2017-05-19 13:38:10,739"


it appears to be wanting a traversal license.


The Expressways are X8.6.1 which shouldn't need any additional licenses for CMR integration, but do you need traversal licenses to do this?  Do later Expressway version resolve this?


Thanks.
