SIP phone in SRST

[Anil Sharma]

Hello,

I have worked on configuration of SCCP phones in SRST.

Can anyone help me what are the different configs that are needed to make SIP phones work in SRST ?

Many Thanks

Regards,

Anil Sharma

CME as SRST? Or regular SRST?

Can you post your SCCP configuration?

You need to configure SIP SRST, that's a completely separate configuration in IOS than SCCP SRST.

max-pool is equivalent to max-ephone. Aka maximum number of phones that can register to either of the SRST sub instances.
