I'm experiencing a voicemail message recording issue. I am getting what I've seen described in cisco documents as 'robotic voice' or 'synthetic voice' for many messages being recorded. I thought it might have something to do with the fxo port gain, but I've experienced this even with a voip call via a sip provider.
I have 2 spa400 and a spa9k. I can replicate the problem by connecting in via AA and then to VMM. then sending a message to a voicemailbox from within the 4K. Any thoughts on this? I can leave message after message on the same call-in, and some have the issue and some don't. Any thoughts? -Don
