we have configured CUCM 9.1 and 2911 router as gateway on HO and configured soft VPN on the same router, we have uc 540(CME) on remote site, now calls between HO and UC 540 is totally fine,but when we connect through VPN and calls to Remote site (CME) we are having one way audio we are enable to hear remote site (uc 540), on the remote site we are sing SIP phones SPA 504 and 525.and on HO we are suing Csico communicator and cisoc 7945 phones.
kindly help me to resolve the issue as soon as possible.

For one way audio issues, apart from the normal ping tests you need to endure that there is no device / config blocking the RTP/UDP ports. You can take packet captures on the site where there is no audio and check if the RTP stream from the main site is actually reaching it or not. We can follow a hop by hop approach to track it to see where the RTP stream is lost.
