Hi Chris -
I am getting to my wits end with these phones (and so is my boss). I amI'm amazed it got that far with Polycom. My experience is that they do not support these phones at all.
getting an random echo on these phones and I have an issue opened with
Polycom and its been in their research and development department for
almost a month with no results.
What version of * are you using? I'm using 1.0.2 with Polycom 1.3.4 firmware on IP600's and I haven't seen any of these problems. If you'd like the 1.3.4 version of the firmware, just let me know off list.I have noticed that I get a message "RFC3389 support incomplete. Turn off on client if possible" in asterisk. I have researched this and made the change in ipmid.cfg (see below), but I am still getting this RFC error.
--- ipmid.cfg ---- <RTP qos.ethernet.rtp.user_priority="5"/> <RTP qos.ip.rtp.min_delay="0" qos.ip.rtp.max_throughput="0" qos.ip.rtp.max_reliability="0" qos.ip.rtp.min_cost="0" qos.ip.rtp.precedence="0"/> <RTP tcpIpApp.port.rtp.filterByIp="1" tcpIpApp.port.rtp.filterByPort="0" tcpIpApp.port.rtp.forceSend="" tcpIpApp.port.rtp.mediaPortRangeStart=""/> ----- end ----
I am just wondering if anyone can help me troubleshoot the echo and RFC
error so I don't have to pull the entire phone system out and purchase
an entire new system.
Stupid Question: Is the echo on all calls or just on calls to/from the PSTN? If just PSTN calls, do you have any echo cancellation enabled?
Thanks, Noah
