Tried something similar to that already but it didnt work<br />
<br />
Did discover the problem in the end, I didnt add the below config lines to the gateway router. Works without any problems afterwards.<br />
<br />
mgcp bind control source-interface FastEthernet0/0<br />
mgcp bind media source-interface FastEthernet0/0<br />
<br />
Thanks for the suggestion anyway

HI All,<br />
<br />
Having problems configuring Cisco Call Manager 5.1 with a Cisco 2811 MGCP controlled gateway connected to 4 ISDN 2e circuits. Configured the gateway via the GUI and the gateway has successfully synced the config and is talking to Call Manager wihout any problems, the ISDN 2e endpoints are also reporting as registered. Created the nesessary route patteren and line groups etc but when making a call I receive a busy tone. <br />
<br />
ISDN is reporting as &nbsp;'MULTIPLE_FRAME_ESTABLISHE<wbr />D' on the gateway, and q921 messages show TX and RX messages.<br />
<br />
Can anyone help with this?<br />
<br />
Thanks,<br />

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
