Asterisk Dialplan for GSM Gateway Dailout

Question

Asterisk will receive calls (32 concurrent calls) from IAX2 trunk and will send to SIP based GSM gateway for dial out. Here is my current dialplan:

[general]
static=yes
writeprotect=no
clearglobalvars = yes
[block]

[very-3]
exten => _X.,1,RetryDial(,3,2,SIP/${EXTEN:3}@Goip104)
exten => _X.,n,RetryDial(,3,2,SIP/${EXTEN:3}@Goip105)
exten => _X.,n,RetryDial(,3,2,SIP/${EXTEN:3}@Goip106)
exten => _X.,n,Hangup(17)

I googled above syntax

here is my sip.conf:

[Goip104]
canreinvite=no
context=very-3
dtmfmode=rfc2833
host=192.168.101.104
port=5060
call-limit=8
;allow=all
disallow=all
allow=g729,g723
insecure=port,invite
type = friend

[Goip105]
canreinvite=no
context=very-3
dtmfmode=rfc2833
host=192.168.101.105
port=5060
call-limit=8
;allow=all
disallow=all
allow=g729,g723
insecure=port,invite
type = friend

[Goip106]
canreinvite=no
context=very-3
dtmfmode=rfc2833
host=192.168.101.106
port=5060
call-limit=8
;allow=all
disallow=all
allow=g729,g723
insecure=port,invite
type = friend

This works good but requirement is to share gateway priorities. So 1 call goes to GoIP104, second call goes to GoIP105 and so on. With the current configuration, it fills up the GoIP4 first, then it goes to next gateway in priority. I tried setting up the same priority in dialplan but asterisk gives error on that.

Kindly help!
