I'm confused about a question that is in almost every multiprotocol lab. 'Configure the HQ-RTR as an IPIPGW. Calls coming into it from CCM via H323 using G711ulaw and routed out to BR2 CME via SIP using G729. Also, calls coming from CME via H323 using G729 and routed to CCM via SIP using G711ulaw'
My question comes at this part... 'Ensure when calls are coming from SIP to H323 that RFC2833 is properly stripped. Ensure that if calls are coming from H323 to SIP that RFC2833 is used for the SIP side.' So, it's my understanding that in this call flow, calls are only H323 to SIP. I don't see a SIP to H323 call. Am I correct? So then, why would I need the following? dial-peer voice 11 voip destination-pattern 3... session protocol sipv2 session target ipv4:10.1.202.1 dtmf-relay rtp-nte digit-drop h245-alphanumeric <--- Why the digit drop? and h245-alphanumeric? >From what I've read, the digit drop will drop the in band dtmf tones from the >rtp-nte relay, allowing the out of band to pass through. But in this call flow, the call is coming from CCM to IPIPGW as H323, and leaving IPIPGW as SIP. It's my opinion that I would only need the following: dial-peer voice 11 voip destination-pattern 3... session protocol sipbv2 session target ipv4:10.1.202.1 dtmf-relay rtp-nte Am I missing something?
