Tests with MediaRelay

Registration
The provider supports UDP and TCP as transport protocol. The tests were completed using TCP, since UDP is an unreliable protocol and requires all involved network elements to support IP-fragmentation.
CLIP
OK
CLIR
OK
CLNS
OK. Redirection based on the Diversion number or based on "302 Moved Temporary" is not possible. Since CLNS is possible, it has no effect on forwarded or Mobility calls.
codecs
G711A, G711U, G729A, G722, OPUS.
Fax
Transport of faxes to/from the PSTN via G.711A codec was tested successfully. Additionally transport of faxes to/from the PSTN using the T.38 protocol was tested successfully. This is important for the innovaphone Fax-server. Even if the provider supports T.38, it is not guaranteed that all Fax-calls use T.38. However each call using T.38 will save you 2 DSP-licenses on the gateway hosting the Fax-interface.
SRTP
The provider supports audio encryption using SRTP for incoming, outgoing, intern calls.
DTMF (RFC2833)
OK
NAT Traversal
The provider detects clients behind NAT and can handle calls to them without requiring the clients to use NAT-traversal methods like STUN.
Reverse Media Negotiation
OK
Mobility Call
OK
Redundancy
OK
IP-Fragmentation
OK
Large SIP messages
OK
Correct signalling of Ringing-state
OK
Early-Media
OK
Session Timer
OK
Call Transfer
OK
