Reviewing DO as a VPS option for a number of projects.
One of them is Asterisk. Is running Asterisk technically feasible on DO? I did not see any restrictions in the Terms Of Service. But I found no Article/Tutorial on Asterisk, and barely one customer installation question in "Questions" where it wasn't clear if it was solved or not. My guess would have to be that it's not a very common use case.
To install Asterisk + DAHDI from source, kernel source may be required. (Linode talks about Asterisk requiring a paravirt kernel, and some versions of Asterisk appear to require a 1000Hz kernel.) Also I read somewhere that KVM virtualization can interfere with timing to the point that conference calling does not work well.
In any case, can anyone confirm that Asterisk would work fine? best regards -Ricardo
