<br>
I am confronted with the following problem :<br>
<br>
making a call only leasts for about 30 seconds, then the call is ended.
The CLI shows :<br>
<br>
[May 21 14:31:50] WARNING[25345]: chan_sip.c:1980 retrans_pkt: Maximum
retries exceeded on transmission <a class="moz-txt-link-abbreviated" href="mailto:954539948-5060-2@192.168.1.100">954539948-5060-2@192.168.1.100</a> for
seqno 11 (Critical Response) -- See doc/sip-retransmit.txt.<br>
[May 21 14:31:50] WARNING[25345]: chan_sip.c:2002 retrans_pkt: Hanging
up call <a class="moz-txt-link-abbreviated" href="mailto:954539948-5060-2@192.168.1.100">954539948-5060-2@192.168.1.100</a> - no reply to our critical
packet (see doc/sip-retransmit.txt).<br>
<br>
I read about SIP-packets being retransmitted but in the end not being
acknowledged and so Asterisk ends the call.<br>
<br>
<br>
The network is like this :<br>
<br>
analogue phone -- Grandstream GXW4008 -- Linksys WAG160 -- Asterisk
server -- ITSP<br>
<br>

in the router ?? Can it be resolved ?<br>
<br>
<br>
Kind regards,<br>
