Bandwidth reservation on egress realm for emergency calls from "enterprise SBC" to SIP provider

Hello

We have a peering scenario with enterprise SBC (SIP Provider <=> E-SBC <=> MS Lync).
A bandwidth reservation for "emergency" calls (112) from Lync to SIP-Provider should being configured.

As a test we have tried to configure following items:

1. local policy for 112 emergency-number calls with
            source-realm= lync
            policy-priority=emergency
            Policy-Attribute => next-hop= SIP-Provider

 

2. realm-config SIP-Provider
            max-bandwidth=100 (for one call as an example)
            max-priority-bandwidth=100
           
3.  media-profile 
            name                                    PCMA
            subname                                
            media-type                              audio
            payload-type                            8
            transport                               RTP/AVP
            req-bandwidth                       100

     

Result of tests:

1. if no media-profile is configured there is no bandwidth usage on a active call from lync to SIP-provider with
   "show mbcd realms"
    After having configured media-profile calls with PCMA are show in "show mbcd realms" statistic
