Description: I've read about this problem in earlier versions of asterisks, but I have 1.4.41 and it it still appears here.
Problem is that some phones disconnect after 20 seconds of active call with two kinds of warnings appearing:

WARNING[25368] chan_sip.c: Maximum retries exceeded on transmission 805d92a8-c0a80103@(here is ip adress of calling phone) for seqno 2 (Critical Response) -- See doc/sip-retransmit.txt.
WARNING[25368] chan_sip.c: Hanging up call 805d92a8-c0a80103@(here is ip adress of calling phone) - no reply to our critical packet (see doc/sip-retransmit.txt).

or

WARNING[14307]: chan_sip.c:2077 retrans_pkt: Maximum retries exceeded on transmission ODI3NmI0MjU1ZmQ0NWE. for seqno 2 (Critical Response) -- See doc/sip-retransmit.txt.
WARNING[14307]: chan_sip.c:2099 retrans_pkt: Hanging up call ODI3NmI0MjU1ZmQ0NWE. - no reply to our critical packet (see doc/sip-retransmit.txt).

The main thing is that it affects only some phones, but there's тno regularity - it happens with some phones of different companies and in different towns. I've read on forum that it could be the problem with invitation, but it was fixed in 1.4.19 version already.

Thanks in advance for your help.

As the documentation referenced says, this message is just normal error recovery. Without SIP traces demonstrating that the lack of response is due to a bug in Asterisk, which will need to be taken with a supported version, like 1.8.x, there is nothing that can be done.
