Trixbox - no incoming audio with Voiptalk Telephoneman 09-01-06

Can anyone shed any light on this? I've set up 3 trunks - Voiptalk, Voipfone
and Sipgate. With Voipfone and Sipgate I get 2 way audio but with Voiptalk
the other party can hear me but I can't hear them.

Voiptalk CS won't support trixbox at the moment, although they helpfully
sent me a config that another customer had used successfully. If the problem
was across all Carriers I'd suspect a NAT or port forwarding issue but with
just one I'm scratching my head a bit.

TIA

Liam

Are you using SIP on Sipgate & Voipfone but IAX with Voiptalk?

If so, IAX requires a different (single) port to operate.
Have you forwarded TCP / UDP or both?

Looking at their site it appears they support Asterisk, tell them your
using Asterisk and get them to tell you what should be in the *.conf
files and what ports should be set. Make a note, then add it to the
freepbx interface later (will overight *.conf files).

Let us know how you get on.

Calling Jono, What did you do to get Voiptalk working?

Liam's tried my settings which work fine here, but gets this one-way
audio issue.

Funnily, I tried my settings from my normal Trixbox in my experimental
Vmware version, and I'm getting this same issue......

Sorry to answer my own post, but it now works on the vmware version
too.

In config edit->sip_nat.conf I had to add:

externip=myfixedIP (not my dyndnsname)
localnet=192.168.1.0/255.255.255.0 (this would be the same on your
716g)

Calls in and out are working fine

Hi Paul,

I had the above in sip.conf under [general] but with the dyndns name. I
removed it and put it in sip_nat.conf with the IP address. Still no joy.
Re-booted linux/asterisk and made 1 call on Voiptalk - still one-way audio
but subsequent attempts to call on this trunk get the asterisk lady telling
me it's busy...

I'm going out to buy some Strowger switches...

Liam
