Polycom 430 , 501 and 550
Hi List;
Can someone advise me if Polycom support H323 that
work fine with Asterisk? And wether this H323 Polcyom
devices more costly than SIP Polycom.
Also, I am not able to know if new Polycom come with
PoE adaptor so no need for PoE Switch (can use normal
switch that does not support PoE)? Do I need any
special cable for Polycom or normal Ethernet cable?

I need to select a line from the Zap group channel
using the SIP Phone (not FXO and not FXS ports).
ignorepat does not work?
Also, what is the method to let the second dial tone
has another tone frequency?
Regards

No, ignorepat is for FXS ports (FXS ports use FXO
signaling). Also,
ignorepat does not apply to SIP phones, because SIP
phones provide

Switchvox
I just inherited a client that is using a Switchvox system. I normally
install a CentOS based system with freePBX and some custom endpoint
management stuff for Polycom phones. This Switchvox is making me feel a
bit stifled. I am having nightmares of another recent encounter with
Trixbox Pro.
Can I really not ssh into this box? If I could is there anything useful
that I might change

IAXy device
Hi All;
I have been chocked just when I saw some posts talking
about how much the IAXy is bad :) -
So I would like to ask, did any one try it later and
wether it is good or not? I am asking this because I
need to use it as it is NAT Transparent (as I read
also, and I did not try it to see how much it is
transparent).
What about codec? Why it is only support g711 and does
not support compressed

TCP port, VPN and resolving the cutting voice problem
Hi All;
Can I run the IAX on TCP port instead of UDP port?
If I ran IAX in TCP port, and in case my network was having a lot of users doing browse on the internet and downloading, so in that case and if the IAX used TCP port, so the voice will be better than using UDP (because in TCP the lost packets will be resend while in TCP it will not which will cause the voice to be cutting)?
