We have zoiper connected over iax to asterisk in Sydney. The call is to asterisk in New York. The caller in NZ can hear clearly. Nothing in NY.

Here’s the sydney server:

— Accepting AUTHENTICATED call from :
> requested format = speex,
> requested prefs = (),
> actual format = ulaw,
> host prefs = (silk16|ulaw|gsm|g722),
> priority = mine
— Executing [8447@nz-in:1] Dial(“IAX2/n4-270”, “IAX2/sydney”) in new stack
— Called IAX2/sydney
— Call accepted by (format ulaw)
— Format for call is (ulaw)
— IAX2/sydney-8819 is ringing
— IAX2/sydney-8819 answered IAX2/n4-270
