We have been having problems with some coworkers not being able to reliably register their softphones (PhonerLite).
Their softphones sometimes register with the SIP server (our two FritzBoxes serve as two individual SIP servers, each of them with 10 business phone numbers registered and active via Vodafone (ISP).
It seems that this pertains almost exclusively to the FritzBox with the local IP of 10.10.115.1.
Uplink Balancing is enabled, which has been working fine up until recently (since we started experiencing VoIP problems).
The people affected by it the most at the moment are people working from home, which are connected via SSLVPN (OpenVPN).
I'm suspecting a lack of proper Multipath rules to contribute to the problem, but I'm not sure. At the moment, all Multipath rules are deactivated.
Unfortunately, I haven't been able to capture the traffic of a failed registration process so far.
Any help, suggestions, etc. would be appreciated. Thanks.
