Да, похоже на маркетинг. В лабе на CS1 несколько SIP ТГ работают. Что будет под реальной нагрузкой - не знаю.

CPU6 and CS-1 theoritically do not support any SIP accesses (SIP Trunk , SIP Application SIP device, SIP User …) This technical limitation was not applied in the past (not in ACTIS, not in technical doc), before Actic 19.2 |

For Existing system with CPU6/CS-1 + SIP accesses •ACTIS will let you add “NON SIP” feature to your system (so without forcing a CPU replacement, since your system is running well) •ACTIS will force CPU replacement(*) if you add or extend SIP feature quantity(**) •ACTIS will force CPU replacement if you change the OXE version (*) The CPU replacement will force an OXE Release upgrade if your current OXE release does not support the actual CPU: CS-2/CPU7 (**) Even a very small extension of SIP user will trigger CPU replacement |
Так что использование CPU6 и CS-1 с SIP'ом - на свой страх и риск.
