Routing SIP traffic over OpenVPN using different gateways

I am unable to route SIP audio over a point-to-point OpenVPN connection between home and work. The home network is on its own subnet (10.71.73.0/24). The work network is on a different subnet (10.0.0.0/8). Most internet traffic passes beautifully over the VPN. SIP calls do not.
Calls from work (10.0.0.0/8, where the PBX server is) to home (10.71.73.0/24) ring the phone but do not include audio.
Calls from home (10.71.73.0/24) will not establish (the phone gateway reports no connection).
This link is the closest I found to my situation. I generally understand my troubles may be because I am spanning two gateways. I do not understand how to fix the problem.
My home subnet (10.71.73.0/24) is easily changed. I cannot modify my work subnet. I do have essentially full control over both VPN endpoint configurations.

Just checking if you found the solution to the SIP configuration, Also, what client are you using for smart phones?
Your problem is probably that 10.0.0.0/8 and 10.71.73.0/24 are conflicting networks.
Nothing special needs to be done to SIP over OpenVPN. There's usually no NAT so it's easy.
