D430E 安装七号信令问题

如题，asterisk 版本是 1.4.33.1-1，dahdi 版本是 dahdi-linux-2.3.0.1，chan_ss7 版本是 chan_ss7-1.3。整个编译程序均顺利完成。但执行时出现错误，log 里不停地显示 "mtp.c: Got su on link 'l1/15': len 6 buf[3] 0x00"，启动日志如下：

另外想问问你的 dsp 和 osp 值是如何算出来，谢谢。

在 [link-l1]下面填加 sltm => no试下，如果仍有问题，提供ssh给我。我的邮箱：This email address is being protected from spambots. You need JavaScript enabled to view it.
[link-l1]
linkset => ls1
channels => 1-15,17-31
schannel => 16
firstcic => 33
enabled => yes
sltm => no
echocancel => no
echocan_train => 350
echocan_taps => 128

还是不成，系统日志显示 ：
[Feb 16 01:23:47] NOTICE[23850] l4isup.c: T22 timeout (No "circuit group reset acknowledge" from peer) CIC=33.
[Feb 16 01:23:47] NOTICE[23850] l4isup.c: T22 timeout (No "circuit group reset acknowledge" from peer) CIC=49.

因这台服务器还没有对外的资源，暂未能提供 ssh 帐户，我会尽快想办法弄些资源对外，谢谢。

尝试出 call 时系统日志如下：

请问 chan_dahdi.conf 是否也要做设置呢?
