Asterisk is still relevant and will be relevant for a very long time (IMHO)
10 years to make IT in the field very difficult and dangerous. But given the fact that many state offices are sitting on Asterisk , and in 10 years will need specialists

It is not clear what is meant by "developer". If it's a programmer, writing modules or closing bugs in *, that is one direction. If that programmer in Python/Perl/etc, writing system that interacts with * using AMI/AGI/ARI - other. If you're human, pishushih config to * handles optimizing his work - the third.
In any case, going into the direction of "telephony" will have to expand your horizons, to grow. But already there are new horizons - "highload", scalable solutions, etc.
You may need deep knowledge of SIP (guide Goldstein to help) and other telephone protocols - PRI, SS7 etc.

Anywhere telephony is not going anywhere in the near future, as well as e-mail. The platform may be different, but the technology will remain.
Messeneger, including voice, will remain a secondary means of communication in their instructions and the documentation indicates "not to be used for emergency calling".
And if innovations in the telephony will be a little, will need integration with CRM and ERP, security updates, etc.
