Hello everyone!
I need to configure SIP TLS trunk between my CUBE and ITSP.
Do i need to use PVDM, for conversion SRTP>RTP and back ?
If i need to use PVDM, i have pvdm4-32 and pvdm4-64 in my ISR 4331, how to calculate the number of encrypted calls?

RTP<->SRTP interworking does not required DSP resources for routers that are running IOS XE.
Here is the documentation:
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/configuration/cube-book/srtp-rtp-interworking.html
Here is calculator if you do need calculate any type of transcoding/conferencing/DSP resources.
Cataloged under the Cisco Tools & Resources repository the new tool can be directly accessed at https://dsp-calc.cisco.com/
Note: CCO login is required
