UC Proxy not working for PSTN calls and Unity Connection

[Mohammed Asif C Y]

Hi Pro,

I have a CUCM 8.6 and ASA 5510 with 8.4.3 version. I have configured UC proxy and it is working fine for VOIP to VOIP calls. But Whenever i make any PSTN calls (Mobile/Land line calls) there will not be any audio both the ways.

Also i have observed that voice mail feature is not working, not able to hear unity welcome message. When i dial pilot number of voice mail it is getting connected but there will not be any audio.

Any suggestion will be much appreciated.

Regards

Why are you using UC proxy?  That is no longer recommended approach, instead deploy VPN phones as most Cisco phones can run VPN client and connect to CUCM via ASA. Phone Proxy had many challenges and caveats.

HTH,

Hi Chris,

Thank you so much for replying, it is our one of customers requirement and they do not have VPN any connect licenses.

We wanted to achieve this using UC proxy itself.
