5. RTP Connection
− RTP is Non-Recursing by default and it is forced to be
6. DTMF
− Outband signaling only (‘DTMF Type’ in PGM 133 is ‘INFO(DTMF RELAY)’ and
this is called CISCO type)
− If end user terminal can detect INBAND DTMF then the DTMF type can be set
as ‘INBAND’. Anyway the INBAND DTMF tone will be pass through virtual SIP
CO line.
7. DSP implementation for VCOL
− VOIP RTP relay channel usage for DSP facility is same as in case of SIP
extension
− A physical VOIP RTP relay channel is required dynamically when need to serve
MOH, Ringback/Busy Tone, Paging and so on. Normally 1/8 of total SIP CO
channel (1/4 for concurrent SIP CO call and 1/2 for dynamic usage for only in
case of MOH, Ringback/Busy and Paging) is required at least.
