Abstract
The present invention relates to instability problems in circuit switched conferencing, and provides a method for establishing a backup “voice only” telephony link in parallel with a H.320 conference link. The two links between the calling parties is handled as one logical call entity. Audio is muted on the backup voice telephony link when status of the H.320 link is okay. If communication problems are detected on the H.320 link, audio is muted over the H.320 link and switched to the backup voice telephony link instead.
