RTP Encryption

Hello

I have been struggling to get his working ;

Our Setup is

PSTN terminated on Nortel.
SIP Trunk between Nortel and cisco .
SNOM SIP Phones terminated on Cisco CME Version 7.1

Cisco IP Phones are also terminated on Cisco CME.

When I enable "RTP Encryption:" on SNOM SIP Phone then voice works one-way

i.e for calls initiated from Snom to Cisco Phones ( both phones are configured on CME )

If calls are initiated from Cisco Phone to Snom Sip Phone then voice works perfectly.

If I disable "RTP Encryption:" then calls from PSTN to SNOM endpoints doesnt work, it rings with no voice.
If I press the hold key for 5 sec and release then voice starts working.


What tweak is needed on Cisco CME to get this working.

thanks

Nasr

Encryption is supported only with Cisco phones in SCCP mode.
