[Freeswitch-users] grandstream Gateway installation question

[Sherif Omran]

Dear all,

I have a grandstream GXW4104 gateway (voip-landline gateway) and i have problems in installing it. 
The gateway (GW) registers as an extension (1005) to my server. I need to send landline calls to extension 1005
and change the SIP header (effective caller ID) to the new landline number (ex: 0352209xxx) 

could you help me with the dial plan?

thank you
regards,
Sherif
