[cisco-voip] CUCM SIP To PSTN

[Jorge L. Rodriguez Aguila]

You can, but unless, you want to open your entire network to the provider, you should not as the Signalling will be SIP from the CUCM to the Media GW on the CUCM but the RTP will be from your phones directly to the Telco Media GW.

Subject: [cisco-voip] CUCM SIP To PSTN

Hi everyone,

  I know with h.323 gateways in CUCM, you have to configure dial peers on each gateway and for each CUCM.  Is it possible to create a SIP trunk directly from CUCM to the Telco?  Without having to do any dial peers on the gateway.  Or would it CUCM SIP <> SIP GW <> SIP PSTN, with SIP dial peers on the SIP GW for both CUCM and the PSTN?

Thanks,

Bill Hendrix
