I’ve suffering cut offs after 6 or 7 seconds a call is answered, incoming calls are working fine, but outgoing ones show the gollowing messages when are being dropped:
[2013-05-15 12:55:14] WARNING: chan_sip.c:3641 retrans_pkt:

[2013-05-15 12:55:14] WARNING: chan_sip.c:3670 retrans_pkt: Hanging up call ZjJkZjlkZWMyZTE4ZmY2NWZlZTExNDM1MDRhMTY4MTc. – no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions). This is happening with my PBX hosted on an external network and peers on my local network.
It seems the SIP ACK is not being received properly.
I’m using asterisk 126.96.36.199 on Debian 6.0.6 and 188.8.131.52 on CentOS 5.9
