Thanks, I've got one *9306
. Everything works fine in the first try of my SIP-code. I've tested to call my PBX from PSTN gateways as well.
Your problem seems to be due to the configuration in your own SIP server. You have not ever been successful to make an inbound call to *8604xxxx, have you? It does not work because you SIP server does not accept calls from SIP Broker. Follows are what I did for my Asterisk PBX, not sure if you need them:
In sip.conf:
[sipbroker]
type=peer
context=sipbroker_inbound
fromuser=421
;fromdomain=www.werty98.homelinux.com
fromdomain=60.240.116.59
host=sipbroker.com
port=5060
incominglimit=3
insecure=invite
nat=yes
canreinvite=no
In extensions.conf, you need to define the context [sipbroker_inbound]. For example, if you want to enable calling *8604271077 from SIP Broker's partners, the extension 271077 must exist in [sipbroker_inbound] in your dialplan.
Cheers,
