Outgoing routes not working (logs attached)

Every time I dial out from a sip phone using the out route _9|. this is logged and nothing happens…

Setting NAT on RTP to 0
chan_sip.c: Checking SIP call limits for device 201
chan_sip.c: Stopping retransmission on ‘596167142-494926e7@’ of Response 2: Match Found

any ideas?.. Thank you.
