Queue SIP Peers

Hi.
I am having a strange problem where some SIP peers (specifically mobile sip clients android/iPhone) are not being called when in queue.

When those SIP peers present in queue i get this message in console

[May 14 12:54:57] WARNING[929]: chan_sip.c:3996 retrans_pkt: Retransmission timeout reached on transmission wiki.asterisk.org/wiki/display/ … nsmissions

If peers removed no error messages printed.

Other from that outside queue all peers work fine inside or outside of internal network.

Am i missing some configuration?

Hi.
Show us the output of

and

sip show peers

with those problem mobile SIP peers.

If you call these peers directly (like ‘Dial(SIP/xxx)’ , not from queue) - are they working fine?

Here is the output

pbx*CLI> queue show TechSupport TechSupport has 0 calls (max unlimited) in 'ringall' strategy (0s holdtime, 283s talktime), W:0, C:2, A:1, SL:0.0% within 0s Members: Sip/Panos (ringinuse enabled) (Not in use) has taken no calls yet Sip/oleg (ringinuse enabled) (Not in use) has taken no calls yet Sip/olegmobile (ringinuse enabled) (Not in use) has taken no calls yet Sip/helpdesk1 (ringinuse enabled) (Not in use) has taken 2 calls (last was 4317 secs ago) Sip/helpdesk2 (ringinuse enabled) (Not in use) has taken no calls yet Sip/helpdesk3 (ringinuse enabled) (Unavailable) has taken no calls yet Sip/helpdesk4 (ringinuse enabled) (Not in use) has taken no calls yet No Callers
