I've got logging turned up, and it appears that FS is doing the right
thing, but PointOne (my termination provider) isn't honoring it.<br>
<br>
I am doing transcoding on some calls (GSM or G726-32 on the phone, PCMU
always out to PointOne).<br>
<br>
If you want to test, I would be happy to add your IP to my proxy's
trusted IP list for a time so you can route calls out through it.
Contact me off-list and I can get you (or Brian) set up on it.<br>
<br>
<br>
This was testing with dtmf-type set to rfc2388 for both my internal and
external sofia profiles. Phones register on internal and calls go out
through external. Here are the logs from a couple of digits:<br>

INBAND is not a function of the sip module it's implemented on top of

Are you doing trans coding or different ptimes between the 2 legs?<br>

you might want to turn up the debug log "press f8" and you will pretty
verbose logging of the 2833.<br>
also consider taking a pcap of the network traffic.<br>
<br>
What is the provider? 2833 is notoriously done wrong to the point that
doing it exactly right can put you at a disadvantage.<br>

I've been having a problem getting DTMF passed through from registered<br>
phones to my termination provider. Sometimes it works, sometimes it<br>
doesn't. My provider is set for rfc2833.<br>
<br>
In looking through the mod_sofia.conf.xml file, and the sofia sources,<br>
it appears that the only two options for DTMF are info and rfc2833.<br>
I've tried various combinations and the only thing that ever seems to<br>
even sometimes work is if pass-rfc2833 is set to true. I've tried this<br>
with Linksys SPA 942 phones, Grandstream GXP 2000 phones and Cisco 7940<br>
phones. Doesn't seem to make a difference. I've also tried various<br>
dtmf-durations and that didn't seem to have an effect either.<br>
<br>
However, after doing various searches it appears that not explicitly<br>
setting a dtmf-type in a sofia profile, it defaults to using inband
DTMF.<br>
<br>
Is this correct? If inband DTMF is the default, then I will have my<br>
termination provider switch my account over to using inband instead of<br>
rfc2833.<br>
