[asterisk-users] Asterisk hangs up SIP call after 6 200 retransmits

I have the following scenario:
PSTN gateway (202.180.nnn.nnn) -> OpenSER 1.0.1 (147.202.nnn.nnn) ->
Asterisk 1.2.16
(203.89.nnn.nnn)
When an incoming call is received, often (but not always) Asterisk repeatedly
sends a SIP 200 OK message and eventually hangs up the call.

sip.conf
[general]
port = 5060           ; Port to bind to (SIP is 5060)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
externip = 203.89.nnn.nnn
disallow=all
allow=ulaw
allow=alaw
language=nz

[DLS]
username=6499777777
type=peer
host=domain.co.nz
context=from-trunk
canreinvite=no

Note that Asterisk registers with proxy:
6499777777:password@conversant.co.nz/6499777777

[asterisk-users] Asterisk hangs up SIP call after 6 200 retransmits

One potential reason could be that the ACK request being sent to
Asterisk is malformed. Notice "branch=0" in the top Via. This should
start
with "z9hG4bK" magic cookie since the INVITE was an RFC 3261
transaction.

While "branch=0" is valid in RFC 2543, I don't think an INVITE can
start-off
as RFC 3261 and then the ACK can switch over to RFC 2543 in the middle of
the transaction. Clearly, Asterisk is dropping this ACK on the floor.

[asterisk-users] Asterisk hangs up SIP call after 6 200 retransmits

I have the following scenario:
PSTN gateway (202.180.nnn.nnn) -> OpenSER 1.0.1 (147.202.nnn.nnn) ->
Asterisk 1.2.16
(203.89.nnn.nnn)
When an incoming call is received, often (but not always) Asterisk repeatedly
sends a SIP 200 OK message and eventually hangs up the call.
sip.conf

port = 5060           ; Port to bind to (SIP is 5060)

[asterisk-users] Asterisk hangs up SIP call after 6 200 retransmits

>One potential reason could be that the ACK request being sent to Asterisk is
malformed. Notice >"branch=0" in the top Via. This should start
with "z9hG4bK" magic cookie since the INVITE was an RFC >3261
transaction.
>While "branch=0" is valid in RFC 2543, I don't think an INVITE
can start-off as RFC 3261 and then the >ACK can switch over to RFC 2543 in
the middle of the transaction. Clearly, Asterisk is dropping this ACK >on the
floor.
OK. But in the calls that don't get dropped, the "branch=0" is
present also. See below for an example:
