[Asterisk-Users] IAX2 calls failing one way.

[Mike Dent]

Hi,
I'm having trouble getting IAX calls through in one direction. On the
receiving end I see:-

Rx-Frame Retry[ No] -- OSeqno: 000 ISeqno: 000 Type: IAX     Subclass: NEW
   Timestamp: 00014ms  SCall: 00001  DCall: 00000 [1.142.164.215:4569]

I have a context in extensions.conf called [from-dave]

Any clues as to why this is failing?
thanks
