I'm trying to connect a Snom to an NEC sl2100. I have the Sip third party license. I've created an IP extension 126. I've followed the: Configuring a VoIP Phone Using Automatic Registration on the NEC SL2100 or SL1100 from my distributor. I have an IP address for the Snom and have connected to it and done or attempted to register my extension with identity 1. I've saved the programming on the Snom but it won't register. I have not changed the Security and Admin password. Do I need to do this to continue? Under Registar, I put the IP address of the PBX 192.168.1.xxx. Does it need to have a :5060, :5080 etc addition? I'm missing something in programming somewhere.

Any help would be awesome.

My notes when I registered sip phone

84-26 VOIPDB setup
10-12 IP network setup
15-05-16 SIP phone password!

3rd party SIP devices are port 5070.

Nice. I did not populate 15-05-16 with a password. 84-26 does have a unique address within the subnet and 10-12 looks good too, so when I go back onsite, 15-05-16 hopefully will do the trick.
Thank you

Thank you.

We had to go to the Snom, Identity 1, SIP, Support Broken Registrar, Turn On, to get it to register.
