Define two peers in sip.conf, one with canreinvite=yes and the second
with canreinvite=no. Then you can route your calls with or without
reinvites depending on the dialed number. Like:

[provider-reinvite]
type=peer
host=external_sip_server.com
canreinvite=yes
...

[provider-noreinvite]
trype=peer
host=external_sip_server.com
canreinvite=no
...

exten => _1[0-4]X0.,1,Dial(SIP/{EXTEN:4}@provider-reinvite)
exten => _1[5-9]X0.,1,Dial(SIP/{EXTEN:4}@provider-noreinvite)
