I would sniff UDP packets with tcpdump and see what is going on: separately in 10.24.102 and 10.24.100 segment.

Do you have any general NAT settings in sip.conf, like externip and local network etc? How about RTP port range?

It would be easier to understand your setup if you post your sip.conf, as well as phone's <MAC>.cfg file (which may be too big for this newsgroup - email is fine).

Also, asterisk sip registration and error messages would give us some more info.

Hello Tim,

You are saying that: phone is on "10.24.102.0/24" and Asterisk resides on "10.24.100.0/24". Honestly, I see at least one hop forwarding here and possible network issues right away.
At one moment, not in a NAT environment, but having phone IP 172.16.100.xxx and Linux server ip 172.16.1.xxx - I had to add nat=yes in sip.conf in order to get the phone to work.


Sincerely,
Andrei

Theres no NAT going on here. Just 1 router in between, phones reside on
10.24.102.0/24 Asterisk resides on 10.24.100.0/24, so this isn't a NAT
problem. Any other ideas?

Tim,

You may see description of new 1.3.4 firmware at polycom.com (check - http://www.polycom.com/common/pw_cmp_updateDocKeywords/0,1687,3641,00.p


d


f ) released in October.

Though, it was proven over time that troubles with a SIP phone like


"not


hearing" one side or the other is NAT related problems. You may want to





investigate firewall setup. I am not saying it is not phone related,


but


the phone would be the last one to blame.

Also, may I express my feelfings about Cisco and Polycom - not allowing





direct firmware download for their phones - that sucks big time. I will





get the firmware this way or the other. They just force me to waste my time again and again contacting their dealers and searching the internet. That should just enrage customers, in my opinion. Are they so





big, they do not even care?

Sincerely,
Andrei

Any idea if 1.34 fixes the problems with the phones being up for long
periods of time and weird call problems (I cannot hear remote caller,
but they can hear me) ?

Hi Chris,

First of all, you need to configure ftp or tftp and watch syslog
closely -
what the phone is looking for at boot time. You would need to put




config




files into (t)ftp directory, named according to MAC address of you
phone.
XML and Web is really weird - they do not even share same config data.
For
example, I had to change address of SNTP server (clock) and it still




was




showing as 'clock' on Web admin page for the phone. I will email you




the




config files I got from a good fellow from this list not so long


ago...


and
those config files do really help!

Also, I suggest that you upgrade your SIP firmware if you have not


done


it
yet. I got the Polycom 500 with firmware which was very old and
incapable to
work with asterisk. Mine is 1.3.1 now
(http://www.freedomphones.net/polycom/files/).

If anyone has SIP firmware 1.3.4 - please make it downloadable




somewhere




on
the internet?

Thank you,
Andrei

Hey All,

First Time Writing.

I'm trying to set up my IP500 phones to register SIP with *. I input all the (I assume) correct data in to the fields on the Web


Interface.










And I get no notification that the phone is even attempting to register, no failed messages etc. I have read that the Web interface




is














crap and the XML config files is the way to go. Does anyone have a basic config file that doesn't change any defaults? I couldn't seem


to








find
one.






Extra Info:
Server is 192.168.0.3
Phone name/ext I want to be 301

Thanks,
Chris Cherry
