Hello, team
   I have installed phonerlite 1.72.
  And have below test set up:
   SBC----(sip)----Proxy-----Phonerlite

   After Phonerlite receives invite initiated from SBC across Prosy, the call is established.
   But after I press hold on phonerlite, I find that phonerlite sends out in-dialogue reinivte directly to SBC which bypasses Proxy.
   The invite sent by Proxy to phoerlite has below record-route format:
Record-Route: <sip:.8d7a6c58-48eea5b2-fd21013a-b888de35@ip-of-sbc:5060;maddr=ip-of-proxy>

   According to my knowledge, phoerlite should send out reinvite to the maddr which is the proxy, but now it sends out to the record route URI which is the SBC.
   Is it a phonerlite bug ?
