NAT Issues - Elastix



  • Hey guys,

    Having some issues with 2 Cisco IP Phones registering outside the network to a Elastix box. Both phones registers fine they are:

    -Able to make outgoing calls with no audio

    -Elastix server hangs the call up few seconds into a call with related error in CLI:
    [2016-07-06 21:41:07] WARNING[4298]: chan_sip.c:4030 retrans_pkt: Retransmission timeout reached on transmission 001b2a8a-177d000a-e4d4ec6b-b77d333e@ <ip-removed>for seqno 102 (Critical Response) – See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
    Packet timed out after 6400ms with no response
    [2016-07-06 21:41:07] WARNING[4298]: chan_sip.c:4059 retrans_pkt: Hanging up call 001b2a8a-177d000a-e4d4ec6b-b77d333e@<ip-removed>- no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions).

    I have attached screenshots of my config.

    Just wanted to confirm if my settings are correct. I have made changes to Elastix SIP NAT files adding relevant details. Since I doubt there is a issue with my Elastix server, as the same config worked with my modem/router before I switched to pfSense. Any assistance would be appreciated.

    Thanks,

    Richard.
