Motorola 5121e SIP problems

Hello everyone,

This is my first post on this forum which I was reading a lot lately. I am pretty new to all the modems and sip configs and naturally I came into a problem when I tried to activate SIP on Motorola 5121e. With Cisco EPC2203 I didn't have too much problems, since documentation is better and support is like 100 times better as well.

Basically 5121e wont accept sip config file. Modem is flashed with SBV5121E-SIP-1.0.7-SCM-06-CBNGA01-SHPC-NNEMN.p7 firmware and it is working just fine. I am using this basic config in modem:

Main
{
NetworkAccess 1;
SnmpMibObject docsDevNmAccessIp.1 IPAddress xx.xxx.xxx.xxx ;
SnmpMibObject docsDevNmAccessIpMask.1 IPAddress xx.xxx.xxx.xxx ;
SnmpMibObject docsDevNmAccessCommunity.1 String "public" ;
SnmpMibObject docsDevNmAccessControl.1 Integer 2; /* read */
SnmpMibObject docsDevNmAccessInterfaces.1 String "@" ;
SnmpMibObject docsDevNmAccessStatus.1 Integer 4; /* createAndGo */
SnmpMibObject docsDevNmAccessIp.2 IPAddress xx.xxx.x.xxx ;
SnmpMibObject docsDevNmAccessIpMask.2 IPAddress xxx.xxx.xxx.xxx ;
SnmpMibObject docsDevNmAccessCommunity.2 String "private" ;
SnmpMibObject docsDevNmAccessControl.2 Integer 3; /* readWrite */
SnmpMibObject docsDevNmAccessInterfaces.2 String "@" ;
SnmpMibObject docsDevNmAccessStatus.2 Integer 4; /* createAndGo */
MaxCPE 2;
UsServiceFlow
{
UsServiceFlowRef 1;
QosParamSetType 7;
TrafficPriority 1;
MaxRateSustained 3584000;
SchedulingType 2;
}
DsServiceFlow
{
DsServiceFlowRef 101;
QosParamSetType 7;
TrafficPriority 1;
MaxRateSustained 3584000;
}
}

For mta config I was searching a lot on the web and I also got example with Motorola sip firmware zip, but neither of them is working. I tried many different configs with different parameters, but I always seem to be missing something. Latest config I made, which is pretty similar to Cisco 2203 one I am using is this:

Main
{
MtaConfigDelimiter 1;
SnmpMibObject enterprises.4491.2.2.1.1.1.7.0 Integer 1; /* mta enabled */
SnmpMibObject ifAdminStatus.9 Integer 1;
SnmpMibObject enterprises.1166.1.200.13.2.1.1.14.1 String "x+T" ; /* Digit Map */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.2.1 String "123123123" ; /* username */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.3.1 String "123123123" ; /* display name */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.4.1 String "123123123" ; /* auth name */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.5.1 String "123123" ; /* password */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.7.1 Gauge32 5060 ; /* proxy port */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.10.1 String "10.10.10.10" ; /* sip registrar address */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.6.1 String "10.10.10.10" ; /* sip Proxy address */
SnmpMibObject enterprises.1166.1.200.13.2.1.1.20.1 Integer 1 ; /* use codec table - 1(true) */
SnmpMibObject enterprises.1166.1.200.13.2.2.1.3.1 Integer 6 ; /* pcmu */
SnmpMibObject enterprises.1166.1.200.13.2.2.1.3.2 Integer 3 ; /* g729 */
SnmpMibObject enterprises.1166.1.200.13.2.2.1.3.3 Integer 9 ; /* pcma */
MtaConfigDelimiter 255;
}

But mta is not getting activated. When I telnet to modem and run debug option I get this:

MTA gets an ip address before that and I can see it on cmts, but it obviously doesnt want to accept config file.

I would really appreciate some help if anyone was using this modem with sip. Some config examples would also be appreciated. I read http://www.docsis.org/node/1126 a lot and I went through my config according to that many times, but no luck.

Thanks a lot.
