Summary
SIP Provider: Winitu
The provider does not support all required innovaphone features.
However, this provider has achieved 79% of all possible test points and some remarks have to be made.
Winitu:
- G711U is not supported offnet(calls to PSTN) since within Europe this is not a custom codec. Onnet(calls within provider network) Winitu is codec independent, User Agents are free to use any available codec.
- Winitu does not provide an early media message like This number is incomplete. Instead it provides a 404 error code when a dialled number is incomplete.
Supported Codecs by the provider:
- G711A
- G729
- T.38
Features:
- Direct Dial In
- Fax over IP (T.38) (NOT TESTED!)
- DTMF
- NAT Detection (NOT TESTED!)
- Hold/Retrieve
- Transfer with-and without consultation
- Blind Transfer
- Broadcast Group & Waiting Queue
