[Asterisk-Users] Grandstream Handytone 286 RTP Problems

[Mike Machado]

I am trying to get the handytone 286 to make a very simple call to * and
having problems. It registers with * just fine, but when I place a call
(to echo test, for example), the RTP stream seems to have problems
opening. Here is there error I get in *:

WARNING[98311]: File chan_sip.c, Line 464 (retrans_pkt): Maximum retries
exceeded on call 20d1c411-e210-5f3d-3f88-19035c8fcb26 at 192.168.2.6 for
seqno 0 (Response)

When doing traces with ethereal, I see successful SIP and SDP
handshakes, but when * sends handytone RTP packets, I see a ICMP Port
Unreachable messages sent from Handytone to * regarding the UDP RTP
packet. * then gives up and I see a BYE from *, which handytone acks.

Handytone config is default except obvious SIP registration parameters.
I also have a Sipura SPA2000 and everything works perfect for that one,
same extension and everything (not at same time of course).

sip.conf entry:

disallow=all                    ; Disallow all codecs
allow=ilbc
allow=ulaw                      ; Allow codecs in order of preference

[131]
type=friend
host=dynamic
reinvite=no
canreinvite=no
qualify=300
callerid="handytone <131>"
mailbox=131
nat=0


Handytone info:

Software Version:    Program--1.0.4.17    Bootloader--1.0.0.11
HTML--1.0.0.19


Both on same subnet, no NAT. I have two Handytones, both exhibit same
symptoms. 

Anyone else have this problem?
