Hi, If I understand it correctly you have UC500 series with CME and you would like to change the calling party number on outgoing calls depending on where the call is going. Let me know if I misunderstood it. And give me an example with a drawing if possible. You can accomplish this by creating two separate outgoing dialpeers and adding translation rules to them outbound direction. For example: voice translation-rule 1 rule 1 /match/ /replace/ voice translation-profile translate calling 1 voice translation-rule 2 rule 1 /match/ /replace/ voice translation-profile translate calling 2 dial-peer voice 100 voip destination-pattern 7777 session protocol sipv2 session target ipv4:10.1.1.1 translation-profile outgoing dial-peer voice 101 voip destination-pattern 8888 session protocol sipv2 session target ipv4:10.1.1.2 translation-profile outgoing Translation rules: http://www.cisco.com/en/US/partner/tech/tk652/tk90/technologies_tech_note09186a0080325e8e.shtml Dialpeers: http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a008010ae1c.shtml Let me know if you have any questions.
