    Does anyone have specific experience with the CISCO IP-IP gateway product doing SIP->SIP ?

    I have success with H.323->H.323
    I just tried with SIP in and SIP out with devices that CAN talk to each other. But with the CISCO
    IP->IP Gateway in the middle, I have NO LUCK !

    I am looking to buy a CISCO 2811 to do IPIPGW.

    h323 -> h323
    What is the IOS Version that I need to install and they mentioned on the CISCO site that I need to buy a feature license.

    FL-INTVVSRV-2811(=)

    Mike and Andrew,

    cisco IP-IP gateway platforms support SIP to SIP connection bridging since IOS 12.4(4)T.
    However Cisco warns that the SIP-to-SIP

    And the 12.4 IOS releases require more RAM.

    Just go to config mode, then
    “voice service voip” and then
    “allow-connections sip to sip”
