Summary

The provider supports all required innovaphone features and is therefore qualified as recommended SIP Provider.

Only if the Mobility-feature or WebRTC is desired by the customer, you must enable Media-Relay on the SIP-Trunk. Opposed to a SIP trunk not needing Media-Relay, the transport of all RTP packets by the gateway will result in a higher CPU load for a call. As a result, the amount of concurrent calls is considerably lower compared to a SIP-Provider that doesn't require Media-Relay.

The provider doesn't support the G.729 coder, this might be an issue in locations with low-bandwidth Internet connection.

The PBX is connected to the provider through the public Internet, the tested product "HFO NGN Connect" comes without a dedicated Internet Access Device. According to the provider the amount of concurrent calls is limited when ordering the trunk, currently max. 220 concurrent calls are possible.

The provider offers an additional SIP-trunk product called HFO NGN Business. This product comes with a dedicated Internet Access, used only for telephony. According to HFO, it uses the same SIP server as the tested product "HFO NGN Connect". As a result, the configuration on innovaphone side should be equal. For more details on the product "HFO NGN Business", please contact the provider directly.

NAT - Detection doesn't work for all private networks, see Known Problems for more information.
