[Asterisk-Users] Grandstream Handytone 286 RTP Problems

[SW]

Hi Mike,

I have handytones working OK with *.

My username and name of the context set to same.

Try this;

[131]
username=131
type=friend
host=dynamic
disallow=all
allow=alaw
allow=ulaw

However I am wondering why you get destination unreacherbale from the
handytone. This is nothing to do with SIP negotiation. So you might want to
go look at the RTP trace and see whether those ports are blocked in your
linux box. SIPURA might be using different set of ports.

Also you should upgrade the handytones to a better code. I have 1.0.4.26,
which is known to be pretty stable. If u want the code, search the mailing
list, I remember in December someone posted where to download the code.

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?
