[Asterisk-Users] ISDN Random Hangup Problems

[Stefano Finetti]

Hello,

This morning I just started to have this problem calling from a SIP phone to
a regular phone, using one of the 4 BRI cards (passive) I've in my * box.

It calls regularly, but somewhere after 8-10 secs, it random hangups, or it
hangups immediately after a hold, and so.

I've looked into /var/log/asterisk/messages, and this is the output
corresponding to the hangup:

#####
Jul 30 12:26:22 WARNING[11276]: File chan_sip.c, Line 417 (retrans_pkt):
Maximum retries exceeded on call
4a509c9e-c0af-94d5-2cf8-d9a65493ad21 at 192.168.251.26 for seqno 102 (Request)
Jul 30 12:26:27 WARNING[11276]: File chan_sip.c, Line 2156
(__transmit_response): Unable to determine sequence number from ''
#####

Any suggestion?

I'm quite disoriented in this moment, i initially tought that was a problem
due to the "t" command for the Dial app, (somewhere it played "pbx-invalid"
and hung up), but that part is now solved... still remaining the random
hangups :(
