The deeper I dig the more twists I find.
I noticed that to get HAL's attention via the phone you dial # the only problem I have is I am using a Viking intercom/door entry system (model C-1000B) which also uses # instruction. Viking use it to either disconnect or dial the door station.
So in this case I would wake HAL up but also annunicate the HAL instruction to the door station unit on HAL.
The complete Viking instruction set is here

Is there a work around that makes a workable solution so that both can work without clashing?
Cheers,
Fleetz
