Open the ARS Digit Modification Plans (Optional) page (Call Routing AutomaticRoute Selection (ARS) ARS Digit Modification Plans).Depending on the configuration of your MCD system and the dialing plan that isemployed, it may be necessary to modify the called number for outbound calls to theBroadCloud platform i.e. dialing "9" for an outside line is used.The below profile is an example where "9" is dialed to trigger an Outbound call to theSIP Trunk, i.e. "9" is removed before the call is passed to BroadCloud.Figure 3-11: ARS Digit Modification PlansAudioCodes Mediant E-SBC20Document #: LTRT-12570

Configuration Note3. Configuring Mitel14. Open the ARS Routes page (Call Routing Automatic Route Selection (ARS) ARS Routes).Each ARS Routes profile allows you to define an Outbound route for calls that will bereferenced in the dialing plan of the MCD. The profile you create for calls to theBroadCloud platform should consist of the following.Figure 3-12: ARS Routes15. Open the ARS Digits Dialed page (Call Routing Automatic Route Selection (ARS) ARS Digits Dialed).The ARS Digits Dialed profiles form the dial plan for the MCD system. In an existingMCD system, most of the required profiles should already be in place, in which caseyou will just need to change the Termination Number for each profile to the previouslyconfigured ARS Routes profile ID.The below example shows a system where "9" must be dialed followed by any numberof digits, the call is then routed to ARS Routes profile 1, which is setup to send calls tothe BroadCloud SIP Peer.Version 7.021AudioCodes Mediant E-SBC

Open the Codec Filter Settings page (Maintenance and Diagnostics MaintenanceCommands).By default, the MCD system allows the use of several codecs by the IP handsets.These codecs are generally not supported on the BroadCloud platform.This can cause certain call flows to fail due to the manner upon which Mitel answersspecific SIP requests. To prevent this from occurring, you must disable use of theunsupported codecs using the ADDCODECFILTER command.We recommend filtering the following codecs on the MCD:Figure 3-14: Codec Filter SettingsAudioCodes Mediant E-SBC22Document #: LTRT-12570
