[Asterisk-Users] no sound for inbound calls

[Mike Heininger]

Hi,

I have an Asterisk installation (latest CVS version with channel.c.diff 
patch) that connects to a SIP Provider.
Client is a BudgeTone-100.

SIP Provider <-> * Server <-> NAT Firewall (Linksys) <-> BT100

Outbound calls work perfect.
With Inbound calls the BT rings but I don´t hear the caller and he 
doesn´t hear me.


BT config:
local SIP port:5060
local RTP port:5004
use random port: no
NAT Traversal: yes, no stun server (but have also tried with stun 
server)


This is the corresponding entry in sip.conf ...

[mike]
type=friend
username=mike
secret=fish
reinvite=no
canreinvite=no
host=dynamic
dtmfmode=rfc2833
nat=yes
qualify=yes
disallow=all
allow=ulaw
allow=alaw


If I connect the BT directly to the SIP Provider there are no problems.

Any ideas what I should try?


TIA,
Mike
