[asterisk-users] Annoying Sipura problem?

[Gordon Henderson]

This may not be the right place to ask, but I have an annoying issue with 
a Sipura/SPA1000-2.0.10(e) ATA device connected to an Asterisk box. (The 
system is remote to me, so I've only been able to observe this by dialling 
into a VoIP phone on-site, then run commands on the box remotely!)

First of all it's all working fine connected to an Asterisk box and the 
user can make/take calls via an analogue phone connected to the device 
through the SIP/IAX/Zap lines connected to the asterisk box.

However - everytime the asterisk box does a 'sip reload' the Sipura 
'blips' the phone within about 5-15 seconds of the reload. They've tried 3 
different phones, but they all give a bleep or tinkle, so I guess the 
Sipura is pulsing the line whenever the asterisk box reloads the sip 
configuration.

The Sipura appears to be at the latest and greatest firmware (according to 
my colleague at the far-end), but I've not had any first-hand experience 
of these boxes.

It also appears to "blip" the phone seemingly randomly too - eg. in the 
middle of the night which isn't useful... (We could cope if it was jsut 
when we made configuration changes, but not seemingly at random - which 
I'm guessing is the SIP registration period timing out)

Anyone seen anything like this before? I've had a look at a tshark dump on 
the line, but I'm not convinced there's actually anything wrong with it - 
maybe there's some setting wrong or not set in the sipura's config?

Any clues welcome!

Cheers,

Gordon
