FreePBX: Direct Pickup Retransmission Error

Hi All,

iam running FreePBX, and it works fine, but the direct Pickup wont work.

General Information:
FreePBX with Sirrix Card (4 Channels)
Devices are Yeahlink SIP-T28P

When i try to pickup the call (for example: **16) the CLI show the following error:

[Sep 27 14:07:34] WARNING[2975]: chan_sip.c:3726 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 11 (Critical Response) – See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
Packet timed out after 6400ms with no response

I dont understand, why i have a nat error, all devices are in the same subnet 192.168.1.2/24, so they need no nat.

The complete logfile when i dialed form external to 16 and pick them up with device 80

I hope the error description is good enough, if you missing some input, please tell me.

Since it uses a custom channel driver I don’t think anyone can help you.

I personally have never heard of chan_sirrix

The chan_sirrix belongs to standard (EURO-) ISDN interface-cards.
The problem however seems to be unrelated to those cards, since it clearly mentions a chan_sip retransmission timeout error - so I would guess it has nothing to do with the ISDN-leg of the call but maybe quite a lot with NAT or firewall issues.

I haven’t experienced this myself, but I have a friend who uses Yealink extensively. I believe he mentioned to me that there is a firmware bug in the Yealink directed call pickup programming. Don’t have much more than that, or if it is related to your problem.

We have another Asterisk with a Sirrix Card, on this the Pickup worked correctly (**XX). There is the following Notice in the Logfile too:

NOTICE[7658]: chan_sirrix.cpp:4453 srx_indicate: Don’t know how to set condition 22 on channel Srx/gDW-0x8b48e20

This causn’t the Error.

WARNING[4309]: chan_sip.c:3726 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 8 (Critical Response)
Packet timed out after 6399ms with no response
WARNING[4309]: chan_sip.c:3755 retrans_pkt: Hanging up call [email protected] - no reply to our critical packet

I try to debug with “sip set debug on” for getting more Information about the packets but i can’t retrieve (for fixing the problem).

If need some part of the configuration, pls tell me.

The FreePBX without Pickup isnt a good Solution
