[asterisk-users] pulling my hair out over voicemail

[John Von Essen]

Ok, I have made some progress debugging this. I dont believe it has 
anything to do with asterisk or my phone.  Rather I think it is an 
issues with STUN and/or my Linksys router at home.

The phones I am testing all sit behind a NAT'd firewall, your basic 
Linksys router for the Home DSL user.

The phones all of STUN setup, and the STUN server IP is the IP of the 
asterisk server - which is purely public.

I was able to duplicate the problem with not being able to hear the 
voicemail greeting by doing the following:

Turn off all the phones, and power cycle my Linksys, then turn on 1 
phone. That one phone will then work, and you can hear voicemail 
greeting.

The I turn on the second phone. Then voicemail greeting breaks, and you 
cant hear it when you dial into voicemail. If I unplug the first phone, 
and power cycle the Linksys again, the second phone will begin to work.

So the question is, does this behavior make sense?

I assumed with an STUN server I could have multiple phones behind my 
Linksys firewall, now it appears I can only have one. Is it a Linksys 
bug, or a general known issue? Do I need to run multiple STUN servers?

Thanks
John
