I am having a problem using my smartphone/Bria extension behind our corporate firewall at work. I am not the IT guy, so really don't know much about what is handling NAT for our guest network. In the past I was able to use my Bria extension at work on the company wireless guest network. We have a separate wireless network that accesses our internal servers.
After about 30 seconds outgoing audio from my smartphone drops, but I can still hear incoming audio. Is anybody familiar with this particular symptom? Is there anything I can do with my extension or asterisk so that it can deal with this particular NAT problem? I can use my extension on most other wireless networks I encounter, as well as 3G cellular, so I do not appear to be radically misconfigured for NAT. I have network traversal set to DNS SRV, global IP, in Bria, and UDP keep alive at 45 seconds. My asterisk server has port 5060, 10000-20000 forwarded through my Draytek 2130 firewall at home.
I believe the company uses a cheap, consumer linksys or cisco router that NATs the guest wireless network. It hands out IP addresses in the 192.168.1.XXX range. I cannot, however, identify the router by accessing 192.168.1.1 from a web browser.
Any help appreciated
