Calculating the RTP Port Range for Voice
By default, the RTP port used for voice is 5004 i.e. IpTransportRtpBasePort = 5004
To calculate the RTP port range used for voice :
• RTP range min =IpTransportRtpBasePort
• RTP range max = IpTransportRtpBasePort + 4 * [Number of FXS ports] + 2 * [Number of FXO,
BRI or PRI channels] - 1 , or
• RTP range max = IpTransportRtpBasePort + 2 * [N] - 1 where
• N= 2* nbr of FXS ports + 2* nbr of BRI ports + nbr of FXO ports + 30 nbr of PRI E1 ports +
23 * nbr of PRI T1 ports + 24 * nbr of PRI T1 CAS ports
To calculate the RTP port range used for voice when SRTP and RTP are activated:
• RTP with SRTP range min = IpTransportRtpBasePort
• RTP with SRTP range max = IpTransportRtpBasePort+ 8 * [Number of FXS ports] 4 * [Number
of FXO, BRI or PRI channels] - 1, or
• RTP range max = IpTransportRtpBasePort + 4 * [N] - 1 where
• N= 2* nbr of FXS ports + 2* nbr of BRI ports + nbr of FXO ports + 30 nbr of PRI E1 ports +
23 * nbr of PRI T1 ports + 24 * nbr of PRI T1 CAS ports
