NETSIP-  SIP Trunks

Pre-requisite:

SIP ALG disabled on the customers router

Method:

NETSIP servers use one of many IP addresses, you register to one, however calls may come from another , causing the call to get blocked by your on site router. UDP port 5060 needs to be port forwarded to your NEC, A router must support an allow list from the following 3 x C Classes

103.26.173.0/24

103.26.174.0/24

103.26.175.0/24

DO NOT PORT FORWARD FROM ANY PUBLIC IP ADDRESS,  use allow lists!!

NETSIP use an account number to REGISTER , however INVITES must contain a valid 10 digit CLIP. By default all carrier selections ( 10-29-14 , A-Z ) use the Account “User ID” in 10-36-xx series to REGISTER it also uses the same “User ID” in the “From:” field in the INVITE , we must change the “From:” field in the INVITE to a valid 10 digit CLIP in order to make a successful out bound call

This 84-39 series can only be modified via PC-Pro in the way of scripts. ( SL2100 you can manually change them in PCPro with our using scripts )

In order to modify these values you must:

2. Run the Script 

( you must use “SIP Script” if you are using profiles 2 tru 6. 99% of installs you will only use profile 1, If you are using profile 1 then you can select either Run script or Run SIP Script)
