Sipelia™ 2.12 GA includes the following known issues.
|Siedle||873119||If one or more Siedle intercoms that work behind the Siedle Access
Server have the same extensions as any Sipelia™ entity, then audio issues might
be observed. This issue can occur if, for example, on the Sipelia™ side, a Security Center user is assigned to
extension 1001, and on the Siedle Access server, one of the intercoms also
has extension 1001. This problem is independent of the dial-plan rules and
the trunk configuration between Sipelia™ and Siedle systems. This issue
applies to Siedle Access Server V.4.0.0 Build 1056.
Workaround: Change the configuration of Sipelia™ and/or Siedle Access Server so that they avoid using of same extensions.
