[cisco-voip] Problem transfer call CME 4.0 with trunk SIP

[David Guarnido]

Thanks for your answer Gabriel,

 

That option is active in asterisk, but the problem is:

No ringback occurs on transfer from PSTN calls coming in on IOS gateway.With
Cisco CallManager 4.0 connecting to the PSTN via an SIP gateway, if a call
comes into a phone and it is blind transferred to another phone, the PSTN
side will only receive dead air; ringback does not occur. 

DDTS Number : CSCds11354

Any solution ??

Thanks,

David

Assuming you mean dialing to the PSTN from your cisco. In that case you need
to add the r option to the dial application on your Asterisk box to make it
provide ringback. If it is inbound from the PSTN, then you can do the same
thing on the Asterisk box or you can probably configure your cisco provide
comfort ring as well
 Maybe this helps.

Hi list,

 

I have a setup with a CME 4.0 connected to asterisk box over a SIP trunk.
When a call entries to CME from asterisk, I pick up the call and I transfer
this call, but the calling person doesn´t hear the tone ringback,  he
doesn´t hear nothing.
 
Any idea??
 
A lot of thank you in advance...
 
David
