<DIV><B>Subject:</B> [asterisk-users] OpenVox G400P network registration
problems</DIV></DIV></DIV>Is anybody intimately familiar with the OpenVox G400P
card, or the Quectel M20 <BR>RF modules fitted to it? <BR><BR>I am having
a strange network connectivity issue with just such a card, as
<BR>follows:<BR><BR>The card was previously used with four O2 SIMs, and -- once
I mastered <BR>creating message PDUs! -- worked beautifully, save for the fact
that O2's <BR>definition of "unlimited" as in text messages turned out not to be
the same as <BR>that found in the Oxford English Dictionary
:(<BR><BR>Replacement SIM cards were duly ordered, and this is when the problem
has <BR>manifested itself.<BR><BR>Span 1 will not register a T-Mobile SIM.
Issuing AT+COPS=? shows only O2 and <BR>Vodafone available as operators on this
span. Issuing the same command on any <BR>other span shows Orange, T-Mobile, O2
and Vodafone available. The SIM however <BR>worked properly in a mobile phone
handset. Performing "gsm power off 1", "gsm <BR>power off 2", swapping the
SIMs between these spans and then performing "gsm <BR>power on 1" and "gsm power
on 2" results in the recalcitrant SIM registering <BR>on span 2, and the SIM
formerly from span 2 not registering on span 1.<BR><BR>I'm guessing the Quectel
M20 GSM module on span 1 has got itself into a <BR>strange state; because it was
also necessary to issue "gsm show span 1" to <BR>read the result of the last AT
command (on other spans, the result appears in <BR>the Asterisk CLI). Do you
know of a way of hard-resetting it? (The obvious <BR>"ATZ" does not work,
neither does "gsm power off 1" followed by "gsm power on
<BR>1").<BR><BR>Software versions:<BR>Debian GNU/Linux 6.0.6<BR>Asterisk
1.8.11-cert5<BR>Dahdi 2.6.1+2.6.1<BR>Chan_extra 2.0.5<BR>(Yes, these are all a
bit out-of-date; but they worked before. All I did was <BR>swap over the
SIM cards.)<BR><BR>-- <BR>AJS<BR><BR>Answers come *after*
questions.<BR><BR>--<BR>_____________________________________________________________________<BR>--
