Hi folks, I've got a weird problem. Every day or so, users will tell me that they can't receive voicemail from outside the system. When I look in their voicemail INBOX directory, I see files but they have a small token size like 44 bytes. The envelope information is there for the message and they can listen to that but there is no audio for the message at all.
Internal users can leave messages without problem. I'm leaning towards a codec problem but everyone can receive calls just fine the whole time. Besides, external callers can hear the VM prompts so it's not like the audio stream isn't being setup at all. It's hard to understand how it could be a firewall issue since it will run just fine for a day or so then flake out. Doing a 'restart now' from the CLI solves the problem for a day or so when the problem reoccurs. I'm running Asterisk at Home 2.7 on this system. I've got Disallow=all and Allow=ulaw&alaw in my sip.conf general section. The external provider is Atlasvoice and I've checked with Bjorn and his codec settings are g.729,ulaw, alaw in that order so we shouldn't be having a problem negotiating ulaw. I'm prepared to do more digging but I just thought I'd post to see if anyone had run into this problem before. Googling refers to codec settings and not to intermittent problems like mine. Any assistance is appreciated. -- David Donovan Consultant Fulcrum Solutions
