CME SIP TO CCM calls are not working

[vinayjaiswal]

Hi,

I have implemented CME 7.0 and have registered both SCCP as well as SIP Phones, this gateway is registered to gatekeeper. Calls from SCCP CME to CUCM is working fine, but when i dial from the CME SIP phones to CCM Phone, it disconnects after ringing and does not allow to answer.

I am able to dial from CCM to CME irrespective of protocol being used on the phone.

Expert advise needed.

Thanks,

Vinay

Hi, check if you have this command enable in your CME.

voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
