in order for the router to register with the sip provider it needs a pots

<p class=MsoNormal>In CCM 4.x nothing should be talking SIP to CCM. You
should be just fine doing H.323 to the gateway and SIP out from there.
This is referred to as a CUBE, or IP-IP gateway setup.<o:p></o:p></p>

<div>
<div>
<p class=MsoNormal>If the calls aren't even hitting the router as H.323 ('debug
h225 asn1' doesn't show anything) then you need to look at the CCM config.
If the call is reaching the router but not going out SIP then check to
make sure you have enabled the appropriate 'allow connection' commands under
'voice service voip'.<o:p></o:p></p>

customer of mine has Call Manager 4.x and a few remote sites. One of the
sites was connected via an MPLS network and had a PSTN connection on their
local gateway router. They moved premises and ditched the MPLS connection
and instead of getting a new PSTN line, they went down the SIP road and got a
SIP trunk to an internet provider. All the phones continued to work via
SRST to the local router and the router was configured with the SIP trunk
