Summary

SIP Provider: E-Fon

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

All tests were made without use of Media-Relay or Exclusive Coder.The NAT Detection mechanism and SIP Reverse Media Negotiation work without problems. The SIP Provider supports the G722 codec and does transcoding, by this it allows call to PSTN destinations using G722.

Redundancy is not possible since the SIP Provider only allows one active registration per account at a single time. If we register a second device, it will replace the previous registration.

T.38 is not supported as codec. G711 Pass-through is supported by the provider to send and receive fax calls.

CGPN Suppression is possible, it requires to send as prefix "*31" in the CDPN. This can be automated by an additional Route Table entry.

That being said, the provider has achieved 89% of all possible test points (140/157). For more information on the test rating, please refer to Test Description

Route Settings

Image:EFON_-_SIP_Provider_Compatibility_Test_3.png

  • Force Enblock is required.
  • Special Route to handle Restricted Calls.

Known Limitations

  • No T.38 since it's rejected with "SIP 488 Not Acceptable Here".
  • SIP Privacy ID for CGPN Number suppression not supported, as solution we have to do a route that checks the CGPN for number suppresion (R!) and add as prefix to the CDPN the code *31.
  • Multiple registrations with the same account are not possible, a new registration replaces the previous one making not possible to do redundancy with 2 gateways.
