I’d like to use Spark as an IM/SIP client, but I’ve noticed that the SIP Phone plugin doesn’t send DTMF when a call is in progress – so it isn’t possible to access voicemail, or any IVR system.
Are there any workarounds, or any plans to add this functionality to the SIP Phone plugin if it doesn’t exist? I’ve noticed that this also holds true for the SIP client in Red5 Sparkweb.
Does anyone know if the Asterisk plugin is affected by the same limitation?
Thanks!
