DESCRIPTION

Usually each received sdp-packet has a version number that identifies it. When receiving the same version again the phone can ignore it. However this versioning mechanism does not work reliably with all PBX'es so we introduced the option to keep the phone from checking the version. When version check is off, the phone will compare the entire sdp instead (except for the version).

When setting user_server_type to nortel, ocs or broadsoft -> version-check will be disabled automatically.

VALIDVALUE

boolean like on or off

DEFAULTVALUE

on
