Orbi - no VoIP connection after disconnect and reconnect of Internet connection
Hi all,
I am running an ORBI RBR50 router with three satellites (RBS50). All is running fine so far. I use a Huawei LTE router with bridge mode for internet access.
Firmware is up to date: V2.5.1.16
I use two VoIP adapters, a Gigaset S850A GO VoIP telehone and a Cisco SPA112 adapter, both connect via ethernet to satellites I disabled SIP ALG, forwarded ports to both adapters. So far everything is working.
But: if my LTE connection is terminated by the provider and reestablished by the LTE router, all devices reconnect except both VoIP adapters. After a while I get notifications that the registration to my provider (sipgate.de) failed.
The only workaround so far is to restart the Orbi router.
Is there anything else I can do - I am running out of ideas.
Best regards
Michael
Tried that - no luck.
What works for now: I changed my LTE router in order to have double NAT:
Fixed ip of the lte router (not in bridge mode, but normal access point mode) with 10.0.1.1 and external IP from the provider. DMZ with Orbi 10.0.1.2
Orbi with fixed IP 10.0.1.2 and Internet access via 10.0.1.1
Internally orbi network with 10.0.0.x
Now a disconnect of the LTE connection does not result in a new IP for the Orbi - and the VoIP stay connected even after a new LTE connection (and new external IP for the LTE router)
It seems Orbi is unable to communicate the new internet IP to the VoIP clients (or they don't understand it) if the LTE router is in bridge mode.
Double NAT is not very nice, but a least it is working now.

Can you please describe how SIP ALG was disabled and ports forwarded? Was this on the Orbi or the LTE modem?
I found the SIP ALG disable. Didn't think to look on the page. My fault.
Still wondering how the port forwarding is set up. Do the two phones use different IP ports?
Hi. Thank you for getting back to me. Both VoIP devices have specific adress reservations via DHCP and mac adress identification: Gigaset Phone 10.0.0.201 Ciso 10.0.0.202 I have forwarded 5060 (SIP register), 5160 (SIP) and 5104 (RTP) to the phone, 5080 (SIP register), 5260 (SIP) and 5204 (RTP) to the Cisco Adapter. As mentioned, everything is fine until a reboot or disconnect of the LTE router. Best regards Michael
