Released to production on 2019-12-08:

API.Core¶

• Fixed a bug resulting in 404 for session lookups, possibly causing errors in Registration-Free connections.
• Fixed a bug causing Create DNID in domain API returning a 404 error when the voice application is specified correctly in the request body.
• Create Subscriber API correctly returns 400 error when the SIP password specified is too long.

APP.Core¶

• Handle network failures when connecting to external HTTP services (such as voice applications or Registration-Free control endpoints) by retrying the request up to 3 times.
• Report more CDRs for calls that failed early (for example, during outbound trunk lookup). Now any call that runs a voice application (call routing or otherwise) will have an associated CDR.
• Stability and performance improvements.

Subscribers Gateway¶

• Changes to DoS rate limiter:
  • Make rate limiter configurable per platform environment. The default is 20 requests per minute.
  • Rate limiter has been split into two different algorithms:
    1. Distributed rate limiter that accounts for the perceived subscriber IP address, i.e. considers the private (non-routable) IP address of a client behind a NAT.
    2. A higher limit that is per server, that takes into account just the routable IP address from which the SIP message originated.
• Improved load balancing behavior in the face of high load

Border Gateway¶

• Remove per-gateway, per IP rate limit
• Improved load balancing behavior in the face of high load
