Description: It is possible to create a hash in channels shared variable space like so:

{code}
Set(SHARED(HASH(test_hash,var1))=test)
{code}

And it can be read:

{code}
${SHARED(HASH(test_hash,var1))}
{code}

However, it is unclear how to call the HASHKEYS function in this case. The logical syntax would be:

{code}
${SHARED(HASHKEYS(test_hash))}
{code}

or possibly:

{code}
${HASHKEYS(SHARED(test_hash))}
{code}

But nothing is returned in either case.

I've checked, it doesn't work with hashes in global variable space, either.

The HASH dialplan functions operate on the underlying channel they are executed on. They are not aware of and do not support the SHARED functionality or global variables. Adding support for this would be considered a new feature. If you'd like to add support for this feel free to reopen.
