SPA3102 Loses Registration

Our SPA3102 is registered to a sub PBX and always seems to lose registration. The config is nearly identical to the SPA2102s and PAP2s that have worked fine.

Any ideas?

RE: SPA3102 Loses Registration

I've experienced exactly the same issue here!

After a while it just loses connection. I have to unplug it and plug it back in to get to work again...?

RE: SPA3102 Loses Registration

Likewise for me except with a Cisco SPA504G. Loses connection failed(authentication) and a reboot fixes it.

Hi,
I have several SPA3102s (registering the FXS port) in different locations, they are all rock steady with no problems, just like the PAPs and SPA1001s. I have found that losing registration is more likely due to router or Internet connection than the SPA.

Thanks telagente00. I'll have another look at the router configuration.

I have the phone registering to two extensions and only the PBXes extension loses registration. The other one with a different provider is rock solid.

Is there anything specific to look at in the config of the extension for PBXes? I've basically just got username, password, proxy, and unique port configured.

RE: SPA3102 Loses Registration

Hi,
I have this config on all my SPAs:

<RTP_Packet_Size> 0.020
<Register_Expires_1_> 60
<NAT_Mapping_Enable_1_> No
<STUN_Enable> no
<Handle_VIA_received> no
<Handle_VIA_rport> no
<Insert_VIA_received> no
<Insert_VIA_rport> no
<Substitute_VIA_Addr> no
<Send_Resp_To_Src_Port> no
<SIP_T1> 2
<Reg_Retry_Intvl> 10
<Reg_Retry_Long_Intvl> 20

I have had several faulty SPAs (off ebay) that kept losing registration, also several different routers that appeared otherwise perfect but also kept losing registration. I recall someone else had this problem not too long ago and ended up flashing new software onto the router to fix it.
