2 SIP Voice Gateways? -Internet RRS feed

  • Question

  • I currently have 1 FE running the mediation service for my enterprise voice users.. We are currently bringing up another locations that will be using enterprise voice but our current SIP provider does not offer local DIDs for this location.  I found another internet sip provider which brings me to my next questions..

    my current options wondering whats best and what the experts would do..

    1) Can i just add antother gateway to my current FE ..   Been pondering breaking out a seperate mediation server for mediations services...

    2)Add another site called XXX with its own FE?

    I am currently 100% VMware with all of my lync servers .. have a hub and spoke topology ..  with each spoke holding a small VM farm (dc, file print services etc) with a 50mb mpls back to the main DC .. I do not have an issues adding a FE Lync VM to each site if needed ..  with all web services etc being back at the main DC ..

    Thanks for any info/input

    Dave

  • However, Adding a seperate mediation server to current LYNC deployment is simply and quick way for the new provider. If it is not all the users using the new provider service, you need to create voice policy for the users to use new sip provider service. If all the users will use the new sip service, you can replace the old sip provider with new provider and the new mediation is not needed.

  • Hi David,

    You have mentioned a separate location. If it means a geographically separate location, then yes. you need to have a separate mediation server for that location to optimize the traffic.

    Preferably go for a SBA with with Audiocodes or SBS with a collocated Mediation Server. 

    Thamara.

  • You can add a additional Mediationserver to configure a second route to this sip provider

  • Hi,

    You can add many Gateways possible for a Single Mediation server (for LYNC only). Just add the gateway from the topology Builder and publish. Create the normalization rules for the numbers that should use that Gateway.

    Thamara.

  • But normal media bypass is not supported by a SIP trunk provider, therefore a co-located Mediation server should not be use without media bypass for performance
