Hi, I posted a few days ago about a problem I'm having with my Cisco
2611, NM-2V and VIC-2BRI-S/T-TE. I'm trying to call the Cisco with my
mobile phone and to call to the mobile phone with a softphone. The
softphone is SJPhone running on a Windows laptop, although I've tried
other softphones.
The packets are moving fine from laptop to 2611. When I speak into the
laptop's microphone I can hear the sound excellently on my mobile. I can
also see these packets in Ethereal.
The 2611 also claims to be transmitting RTP packets. However I can't see
these packets in Ethereal and they don't appear to be received by the
softphone -- when I speak into the mobile phone's microphone I don't
hear anything on the laptop.
Here's an example of the debug voice rtp messages:
*Mar 3 03:55:22.269: RTP(2592): fs rx d=192.168.1.101(16384), pt=8,
ts=24E0, s7
*Mar 3 03:55:22.281: RTP(8426): fs tx d=192.168.1.101(16384), pt=8,
ts=293DC956
*Mar 3 03:55:22.301: RTP(8427): fs tx d=192.168.1.101(16384), pt=8,
ts=293DC9F6
*Mar 3 03:55:22.321: RTP(8428): fs tx d=192.168.1.101(16384), pt=8,
ts=293DCA96
In fact, the *only* packets sent from the 2611 are these (transcription
from Ethereal screen):
SIP/SDP INVITE
SIP ACK
RTCP Sender Report
RTCP Sender Report
SIP 200 OK
RTCP Receiver Report
RTCP Receiver Report
ICMP Destination Unreachable
(over a 10-second call)
That last packet is a UDP Destination Unreachable error. Source port
17923, destination port 16387.
I've pasted in my entire config (the only lines that are removed are the
ones containing passwords). I'm positive that there's no kind of
firewall running on the Windows laptop. Could there be some kind of
problem on the 2611 that causes it not to send the packets?
Thanks,
Guan
