Hm, are you sure, or did I just misunderstand the problem? In the past I
had some trouble with the reliability of IAX registration, so I introdued
SIP registration for server B as a backup, and it works just fine:
* server B (dynamic):
register => ServBsip:[EMAIL PROTECTED]
* server A (static):
exten => _0XXX,2,Dial(SIP/ServBsip/${EXTEN:1},30,r)
[ServBsip]
context=from-ServBsip
type=friend
username=ServBsip
fromuser=ServBsip
secret=pw
auth=md5
host=dynamic
nat=no
canreinvite=yes
disallow=all
allow=gsm
Feel free to split type=friend into type=peer and type=user and to
introduce deny/permit entries for the hostname/ip.
Cheers, Philipp
