[Freeswitch-users] No sound on incomming calls

Hi all!

I'm new in the list and I'm starting to test FreeSWITCH at home to learn
how to use it thinking as a alternative to Asterisk.

I've compiled FreeSwitch 1.0.6 and I have been doing some testing with
Iptel.org and FreeSWICH. Outgoing calls to Iptel.org accounts ran
without problems, however I am having trouble with incoming calls.

If, for example, I call from a softphone registered on Iptel.org with a
second account to the Iptel.org account that was registered from
FreeSWITCH, it answers the call but no sound.

The FreeSWITCH server is behind a firewall, but I do not think it's a
NAT problem because then there would be no sound for outgoing calls made
with the softphone registered on Iptel.org.

Could it be a codecs problem?

When FreeSWITCH receives the call, it is redirected to a Grandstream
BT200 phone. To answer the call in the BT200, the softphone indicates
that G711a is being used, but no sound.



Thanks in advance for your replies.

Regards,
Daniel
