I am unable to enable TLS on my Cisco gateway

I try to follow the instructions in the Cisco documentation for configuring to use TLS, but neither the "crypto signaling" command under sip-ua nor the "session transport tcp tls" (either under voice services voip sip or in a dial peer command) are available.  What might I be missing to make these commands available so I can use TLS?  I am running "c2800nm-ipvoicek9-mz.150-1.M4.bin" version of the IOS, and all my configuration occurs via CLI on the gateway.

Hi,

In order to provide SIP Gateway support for TLS you need to use the "SPSERVICES" featureset in the IOS.

Cisco have also pulled support for your IOS version due to multiple bugs

You should upgrade 15.0.1.M7 -SPSERVICES

You will need 128M of flash & 512 M DRAM

HTH
