This is a common issue with all Sipura devices I've seen. I set the registration interval to 5 minutes, so that NAT doesn't interfere. I've done this with Cisco IP Phones, Cisco ATA Converters, and Sipura SPA-1001, SPA-2000, SPA-2100, and SPA-841's. All Sipura's have the same issue, 1 out of every 10 or so registrations will fail. I will suddenly see a Registration failed notice in the Asterisk console, 5 minutes later the phone will go to register, and it works fine. The right userid and password is programmed into the phone. What this leaves is a 5 minute gap when the phone can not be called, if somebody calls that Sipura device within that 5 minutes, they will go straight to voicemail. It's damned annoying. I've tried this on several different interenet connections (At home (where I have DSL and Cable), at work, at my friends home, etc.) and with multiple Asterisk servers and different providers. I've also confirmed this with a sister company we helped build, they've seen the same issues w/ Sipura's, they contacted Sipura about it and Sipura said it was a known issue they were working to resolve, but no ETA. Go figure. I was thinking about going to Linksys's PAP2-NA but I don't know much about it, except they're glorified Sipura's and may potentially have the same issue w/ Asterisk. I don't like how Linksys doesn't support them w/ end users, doesn't offer firmware, makes them a pain to obtain, etc. etc.
I'm trying to investigate going to a different manufacturer, but I don't like the Cisco ATA-186's very much and they're too pricey, so I don't know where to go next. voipsupply has a pretty big collection, maybe I'll order 1 of each for testing. We're about to deploy 150 converters to residential and business users and I can't even find one I like, jeesh. Don't say the IAXY, I only use IAX for Asterisk-Asterisk communication, not for end users. On Fri, 18 Mar 2005 16:41:55 -0800, Wolfgang S.
