VOIP Provider issue

LM-Rafael — Thu, 22 Dec 2022 22:20:35 GMT

Hi everyone,

since yesterday my customer have a major issue with connect their CISCO Dect 210 Base with SIP Provider Placetel.

Yesterday i have switch from a simple Router (AVM Fritzbox) to DrayTek Vigor VDSL2 Modem and CheckPoint 1530 Firewall. This is the first part of a project.

I have check the exceptions which Placetel need and every IP and Port is as rule added.

Under Log - Security log i can see accepted connections and one Device (CISCO ATA) can connect to Placetel but the CISCO DECT Base cant connect.

CISCO DECT IP (100.100.90.225) I know it's not a private network but it's being replaced with the running project.

CISCO ATA IP (100.100.90.224)

I think i found some anomalies, see attachments.

Under Attachments you will find also the temporary Firewall Rules and VOIP Settings.

I dont no why the connection will not work? Do you have any idea?

Thanks and BR

Rafael

Additional information:

CISCO DECT and ATA will auto provisioned by Placetel (over MAC Address) this is also not possible.

What version/build of firmware?
Meanwhile, all the logs show is a connection on SIP (UDP 5060).
Did you confirm with a tcpdump that the RTP traffic is attempted through the gateway (from either end)?

no actually i get no information from tcpdump.

Tomorrow i drive to customer and check every cable and connection from up close.

but i saw today in the tcpdump that there was also a 5060 connection to the placetel server but not anymore. So requests and answers.
