Junction Networks and no inbound DTMF detection on IAX


#1

We finally had our numbers ported over to Junction Networks today from our previous IAX provider and I can’t seem to figure something out. When someone calls in and listens to the main menu, no DTMF tones are recognized whatsoever when the user goes to enter an extension or make a selection. With my old provider this worked without a problem. This only happens on inbound calls. If I call my external PSTN line, then transfer myself over to the same IVR menu, everything works perfectly. I can also dial the menu’s extension from any phone in the office and it works just fine. Anyone have any ideas what is going on?

I’ve made sure the jitterbuffer option was set to no and I’ve also made sure that the connection is made in ulaw. This has been tested from many different phones and many different carriers, all with the same result. Here is my iax.conf file:

[general]
register => myusername:mypassword@iax.jnctn.net

bandwidth=low

disallow=lpc10 ; Icky sound quality… Mr. Roboto.

jitterbuffer=no
forcejitterbuffer=no
tos=lowdelay
autokill=yes

[jnctn]
type=user
auth=rsa
inkeys=jnctn
context=incoming-calls
disallow=all
allow=ulaw
jitterbuffer=no

[jnctn_out]
type=peer
host=iax.jnctn.net
username=myusername
secret=mypassword

Now, here is the output from iax2 debug command when the menu receives a call:
