Support IP Office Modes: SRTP is supported in all IP Office modes.
Supported Phones: It can be applied to SIP and H323 extensions. However, there may be restrictions for some specific models of IP telephone.
Supported for H323 on 9608, 9611, 9621 and 9641 Series telephones.
Supported for SIP on Avaya and 3rd-party telephones.
Supported Trunks: It can be applied to all types of IP lines (SIP, SM and IP Office (SCN)) except external H323 trunks.
Licensing and Capacity: The use of SRTP does not require any licenses or subscription. However, the use of SRTP impacts on the call capacity of the system.
For IP500 V2/IP500 V2A systems with IP500 VCM cards, those cards are used to support SRTP and reduce the impact on the system call capacity. This does not apply to combination cards.
