Managing heterogeneous VoIP networks in medium to large enterprises can be a nightmare. Due to the large number of vendors participating in providing the solution, there can be problems at every stage of the implementation and maintenance issues can arise in a variety of aspects including:
- Network design and configuration
- Device discovery
- Distributed routing & policy enforcement
- Distributed PSTN breakouts
- Multiple VoIP network elements configuration: SBC and MGW
- Multiple dial plans: SfB, IP-PBX, SBC and MGW
- SIP interworking between IP-PBXs A large number of end user policies
Distributed networks present numerous challenges and when it comes to heterogeneous networks where the devices and applications are provided by different vendors, the situation is even worse. Unified Communication systems (e.g. Skype for Business) and the various components in the network such as IP-PBX, SBC and MGW, each have their own static routing, manipulation and dial plan tables.
