[asterisk-users] Dropping Phone Calls

[Todd Reese]

Hi All,


I'm currently having trouble with dropped phone calls.  The following error
message is always in the log.  This is a Grandstream GXP-2000 Firmware
1.1.6.16 .  The Asterisk box is currently 1.4.22-rc5.  The problem has been
occurring on other versions also.


[Sep 19 15:48:02] WARNING[13657]: chan_sip.c:1958 retrans_pkt: Maximum
retries exceeded on transmission 8acaea6dc4c6e9b5 at 10.11.17.23 for seqno
50706 (Critical Response) -- See doc/sip-retransmit.txt.

call 8acaea6dc4c6e9b5 at 10.11.17.23 - no reply to our critical packet (see
doc/sip-retransmit.txt).


Any Ideas?


Regards,

Todd Reese
