A slight clarification (or correct me if in fact you meant something
Option 1: Have _source_ package build-depend on AND _binary_ *-dev
package _depend_ on libsrtp-dev. And do this
Option 2) Have _source_ package build-conflict with libsrtp-dev.
Since libsrtp only builds on some architectures, option 1 really means
add those package relations only on relevant archs. The safest is then
to build-conflict on negated list of supported archs, but if that feels
too complex to handle, I guess that part can be skipped.
I recommend using d-shlibs to auto-resolve the binary relation!

I (obviously) agree, since that was the very point of packaging libsrtp
