SUBSCRIBE failure: unrecognized format: 'multipart/related'

Asterisk Asterisk Support

Hi,

In one of my network I have few SPA942 and one SPA504 with console SPA500S.
Asterisk is 1.4.22. After connecting to the network console SPA500S I have a small problem.

The console works fine but there are many such messages:

[Jun 13 09:42:46] WARNING[2938]: chan_sip.c:15456 handle_request_subscribe: SUBSCRIBE failure: unrecognized format: 'multipart/related' pvt: subscribed: 0, stateid: -1, laststate: 0, dialogver: 0, subscribecont: 'hinty', subscribeuri: ''

What may cause this symptom?

Best regards,

Daniel

A device trying to subscribe to an unsupported service. Identify the device and disable that feature in the device.

A SIP trace may give a clue as to which service and should identify the device.

Thank you. You were right. One of SPA942 had the error in configuration.

Best regards,

Daniel
