There are two modes of SRST - SRST itself (1) and Unified CME in SRST mode (2). Mode (2) provides more features for call-processing. Mode (1) is a bit simplier to configure.

According to SRND:

Unified CME in SRST Mode

When Unified CME is used in SRST mode, it provides more call processing features for the IP phones

than are available with the SRST feature on a router. In addition to the SRST features such as call

preservation, auto-provisioning, and failover, Unified CME in SRST mode also provides most of the

Unified CME telephony features for the SCCP phones, including:

• Paging

• Conferencing

• Hunt groups

• Basic automatic call distribution (B-ACD)

• Call park, call pickup, call pickup groups

• Overlay-DN, softkey templates

• Cisco IP Communicator

• Cisco Unified Video Advantage

• Integration with Cisco Unity with MWI support at remote sites, with distributed Microsoft Exchange or IBM Lotus Domino server

You can find additional information about SRST modes and features in SRND.

Kind regards,
Andrew C.

Thank you Andrew,

But is it possible to highlight to the team which will not work in SRST?

Anything related to External Party connectivity will not work, Such as Mobile Transfer, or other PSTN number related?

[Andrey Chertolyas]

Will not work in comparison to what?

You will be able to configure transfer to mobile number, that's not a problem. But still there are lots of things which you can configure in CUCM and cannot configure using CME SRST. It's better to have the list of features what you have at the moment to say if it's possible to configure the same using CME SRST or not.

Kind regards,
Andrew C.

Hi Jeya,

As Andrew said you will need to dig into SRND for a list of features that are supported on a specific version. However, you can check the following link as it contains feature roadmap for SRST and covers almost all the IOS versions
