Noise at the beginning of a call
I have a customer that has 25 T26 V7 phones behing a Freepbx system version 2.11. They are using a Grandstream GXW4108 for the phone lines. Occasionally on an outbound call we get what appears to be two touchtones playing simultaneously for the first 4 -6 seconds of the call when it is being connected. I have run TCPdump on the Freepbx, don't hear it there. I ran the Pcap on the Grandstream, not there. I have run the Pcap capture on the T26 and it isn't there, although there were some RTP packets out of sequence. (6%). I enabled the jitter buffer in freepbx (200ms), but alas it is still there. I say it isn't there meaning I do not hear the noise when I playback the audio through Wireshark.

Has anyone got any clue what might be going on here?

Thanks for any ideas!
