[Asterisk-Users] FXO gateways on Asterisk

[Dawid Mielnik]

Hi,

I have tested, and still am testing different sip equipment with asterisk.
In my case I'm testing fxs gateways but this is what I have found so far:

- audiocodes mp-104 fxs sip: I'm still testing this one but so far I can not
get it to register properly with asterisk, it fails to authenticate.
Messages are exchanged properly but asterisk just fails to accept its
proxy-authorization data, as if md5 hashed password was not accepted. If you
comment out secret= in sip.conf it registers properly, but there is no
authenticartion. Sometimes I get retransmission RTP errors
(asterisk/syslog). RFC2833 dtmf - ok. I heard that it hungs... ??
Pitty cause it looks solid, works quietly.....

- mediatrix 1104 fxs sip: Registers properly. RFC2833 dtmf signalling.
G729 - ok. Very nice VAD mechanizm. Every now and then I got unhandled sip
request errors (asterisk/syslog). Basically the only bad thing I can say
about this box is that it's pretty loud.

regards,

Dave

I have been struggling with several mediocre SIP FXO gateways on
Asterisk for the past
6 months and have found that each one has at least one major problem
with it.  I am looking
for any success stories using 1 to 4 port SIP FXO gateways on Asterisk.
I need for them
to support RFC2833 DTMF bridging each way and G729 codecs.  Multi-port
FXO gateways
need to have some sort of grouping and/or routing of SIP calls to
specific channels.  So far,
I have evaluated an Audiocodes MP-104 (4-port) and a Multitech MVP-130
(1 port).
If anyone has found something that works in these scenario's, I would
love to hear from you.
I want to deploy many small FXO gateways over a large geographical area
and would
like to find something that actually works.  Thanks for the help!
