IAXy ringing tones?

Anyone’s ever saw that problem?

I have a IAXy and a SIPURA-841, only the IAXy has the behavior described there.

I have two providers, when I call the PSTN using my first provider, everything is fine, I can hear the ringing tone in the phone while the PSTN phone is ringing:

-- Accepted AUTHENTICATED TBD call from 192.168.1.252
-- Accepting DIAL from 192.168.1.252, formats = 0x4
-- Executing Dial("IAX2/iaxy-2002-4", "SIP/sip.babytel.ca/4504440473") in new stack
-- Called sip.babytel.ca/450XXX0473
-- SIP/sip.babytel.ca-3448 is making progress passing it to IAX2/iaxy-2002-4
-- SIP/sip.babytel.ca-3448 is ringing
-- SIP/sip.babytel.ca-3448 is making progress passing it to IAX2/iaxy-2002-4

== Spawn extension (internal, 450XXX0473, 1) exited non-zero on ‘IAX2/iaxy-2002-4’
– Hungup ‘IAX2/iaxy-2002-4’

On the second provider, if I do the same call, there is just no sound until someone takes the call on the PSTN phone, however if I do the same call using the sipura-841 I hear the ringing tone:

-- Accepted AUTHENTICATED TBD call from 192.168.1.252
-- Accepted AUTHENTICATED TBD call from 192.168.1.252
-- Accepting DIAL from 192.168.1.252, formats = 0x4
-- Executing Dial("IAX2/iaxy-2002-2", "SIP/sip.spectravoice.com/450XXX0473") in new stack
-- Called sip.spectravoice.com/450XXX0473
-- SIP/sip.spectravoice.com-ce3f is making progress passing it to IAX2/iaxy-2002-2

== Spawn extension (internal, 450XXX0473, 1) exited non-zero on ‘IAX2/iaxy-2002-2’
– Hungup ‘IAX2/iaxy-2002-2’

I see that on the first provider Asterisk is saying that it’s ringing but not on the second, is my provider at fault?
Anyone has an idea on what I could do on my side?

Thanks

I was able to generate a ringing tone by adding “r” as an option to the dial command, I don’t think this is a recommended setting…

Is there any side effects that I’m not awared of if I’m using this option?
