How to connect Asterisk and HuaWei softswitch?

Hello, Guys:
I installed a asterisk pbx for customer. the asterisk->grandstream gateway->HuaWei softswitch. the HuaWei softswitch supports SIP. I try to dial SIP/IP to connect to HuaWei. But I can not make a call in this way:SIP/IP(wawei softswitch 192.168.1.1). anyone knows how to resolve this problem? please give me a help.
thank you!

you have not provided anywhere near enough information to solve your problem. It’s like calling a mechanic and saying ‘my car makes a funny noise what should I do’ and expecting him to know.

we need your sip.conf entry for the device, extensions.conf entry that’s trying to dial it, and whatever CLI output you get when you try to dial it…
