7. Jasomi Introduces SIP Repair Engine for VoIP Networks
Jasomi Networks has introduced a SIP protocol repair engine for VoIP networks that accepts VoIP packet streams and auto-detects and repairs known incompatibilities before sending the packets forward. The technology also adjusts voice stream contents to account for errors in the destination equipment’s programming, even if the inbound voice packet streams are not themselves in error.
Examples of corrections the repair engine can make include:

  • correcting grammatical inconsistencies such as the incorrect inclusion or deletion of white space in protocol fields
  • correcting phone number formats such as the inclusion or deletion of + in request headers
  • accounting for semantic errors seen in some phones such as incorrect interpretations of the SIP cancel and bye messages
  • implementing packet compaction to avoid fragmentation of UDP call signaling packets
  • converting protocol header fields from upper case to lower case or vice versa to ensure compatibility with equipment that requires one or the other
  • resolving incorrect implementations of DNS SRV record lookups
  • ensuring that protocol fields do not contain outrageous values that could result in undesirable behavior by other equipment in the call
  • limiting the CODECs that can be used in a call

Jasomi’s other products address NAT and firewall problems in VoIP deployments.
